PIC18F6627/6722/8627/8722

The PIC18F6627/6722/8627/8722 Rev. B1 parts you

have received conform functionally to the Device Data

Sheet (DS39646C), except for the anomalies

described below. Any Data Sheet Clarification issues

related to the PIC18F6627/6722/8627/8722 will be

reported in a separate Data Sheet errata. Please check

the Microchip web site for any existing issues.

The following silicon errata apply only to

PIC18F6627/6722/8627/8722 devices with these

Device/Revision IDs:

All of the issues listed here will be addressed in future

revisions of the PIC18F6627/6722/8627/8722 silicon.

1. Module: Master Synchronous Serial Port

(MSSP) — Serial Peripheral

Interface (SPI)

In SPI mode, the Buffer Full flag (BF bit in the

SSPxSTAT register), the Write Collision Detect bit

(WCOL in SSPxCON1) and the Receive Overflow

Indicator bit (SSPOV in SSPxCON1) are not reset

upon disabling the SPI module (by clearing the

SSPEN bit in the SSPxCON1 register).

For example, if SSPxBUF is full (BF bit is set), and

the MSSP module is disabled and re-enabled, the

BF bit will remain set. In SPI Slave mode, a sub-

sequent write to SSPxBUF will result in a write

collision. Also, if a new byte is received, a receive

overflow will occur.

Work around

Ensure that if the buffer is full, SSPxBUF is read

(thus clearing the BF flag) and WCOL is clear

before disabling the MSSP module. If the module

is configured in SPI Slave mode, ensure that the

SSPOV bit is clear before disabling the module.

Date Codes that pertain to this issue:

All engineering and production devices.

2. Module: Capture/Compare/PWM (CCP)

PWM output of 10-bit resolution is not available for

either CCP4 or CCP5 when Timer4 is being used

as the PWM time base (T3CON<6,3> = 01, 10 or

11) for the PWM mode (CCPxCON<3:2> = 11).

Work around

For 10-bit resolution, use Timer2 as the PWM time

base (T3CON<6,3> = 00).

For 8-bit resolution, use Timer4 or Timer2 as the

PWM time base and set the two LSBs to ‘00’

(CCPxCON<5:4> = 00).

Date Codes that pertain to this issue:

All engineering and production devices.

3. Module: MSSP (I2C™ Slave)

In extremely rare cases, when configured for I2C™

slave reception, the MSSP module may not receive

the correct data. This occurs only if the Serial

Receive/Transmit Buffer Register (SSPxBUF) is not

read within a window after the SSPxIF interrupt has

occurred.

For SSP1BUF, the flag bit is SSP1IF (PIR1<3>).

For SSP2BUF, the flag bit is SSP2IF (PIR3<7>).

Work around

The issue can be resolved in either of these ways:

• Prior to the I2C slave reception, enable the

clock-stretching feature.

This is done by setting the SEN bit

(SSP1CON2<0>).

• Each time the SSPxIF bit is set, read the

SSPxBUF before the first rising clock edge of

the next byte being received.

All engineering and production devices.

4. Module: MSSP (I2C™ Master)

If the module is in I2C Master mode and the slave

performs clock stretching, the first clock pulse after

the slave releases the SCL line may be narrower

than the configured clock width. This may result in

the slave missing the first clock in the next

transmission/reception.

Work around

If the module is in I2C Master mode, do not have

the slave perform clock stretching. Alternately, the

master can slow down the SCL clock frequency to

a level where the slave can detect the narrowed

clock pulse.

Date Codes that pertain to this issue:

All engineering and production devices.

5. Module: Enhanced Universal

Synchronous Asynchronous

(EUSART)

In rare situations when interrupts are enabled,

unexpected results may occur if:

• The EUSART is disabled (the SPEN

(RCSTAx <7>) bit = 0)

• The EUSART is re-enabled (RCSTAx <7> = 1)

• A two-cycle instruction is executed

Work around

Add a 2-TCY delay after re-enabling the EUSART.

1. Disable the receive interrupts:

• For RCSTA1 – RC1IE bit (PIE1<5>) = 0

• For RCSTA2 – RC2IE bit (PIE3<5>) = 0

2. Disable the EUSART:

• For RCSTA1 – SPEN bit (RCSTA1<7>) = 0

• For RCSTA2 – SPEN bit (RCSTA2<7>) = 0

3. Re-enable the EUSART (RCSTAx <7> = 1).

(See step 1.)

4. Re-enable the receive interrupts:

• For RCSTA1 – RC1IE bit (PIE1<5>) = 1

• For RCSTA2 – RC2IE bit (PIE3<5>) = 1

(This is the first TCY delay.)

5. Execute a NOP instruction.

(This is the second TCY delay.)

Date Codes that pertain to this issue:

All engineering and production devices.

6. Module: Timer1

When Timer1 is running on the Timer1 oscillator, if

Sleep mode is executed immediately after loading

Timer 1 with 0xFFFF, the Timer1 interrupt will not

get set on the first overflow from 0xFFFF to

0x0000.

All subsequent overflows, from 0xFFFF to 0x0000,

will work correctly.

Work around

None.
