The PIC16F73/74/76/77 Rev. B1 parts you have

received conform functionally to the Device Data Sheet

(DS30325B), except for the anomalies described

below.

All the problems listed here will be addressed in future

revisions of the PIC16F73/74/76/77 silicon.

1. Module: Timer1

 2003 Microchip Technology Inc.

When Timer1 is running in Asynchronous mode

and then disabled, data in the Timer1 register

(TMR1) may become corrupted. Corruption occurs

when the timer enable is turned off at the same

instant that a ripple carry occurs in the timer

module.

This issue only occurs in asynchronous operation.

In synchronous operation, the relevant signals are

latched with the CPU clock and the problem

condition does not arise.

Revision C silicon will correct this issue.

Work around

When Timer1 is configured to operate as an asyn-

chronous counter, care must be taken that there is

no incoming pulse while the module is being

turned off. If an incoming pulse arrives while

Timer1 is being turned off, the value of register

TMR1 may become corrupted.

If an application requires that Timer1 be turned off,

and if it is possible that Timer1 may receive an

incoming pulse while being turned off, synchronize

the external clock first by clearing the T1SYNC bit

of register T1CON (T1CON<2>). Please note,

however, that this may cause Timer1 to miss up to

one count.

2. Module: CCP (Compare Mode)

The output of the CCP module in Compare mode

may become inverted when the mode of the mod-

ule is changed from Compare/Clear on Match

(CCPxM<3:0> = 1001) to Compare/Set on Match

(CCPxM<3:0> = 1000). This may occur as a result

of any operation that selectively clears bit

CCPxM0, such as a BCF instruction.

When this condition occurs, the output becomes

inverted when the instruction is executed. It will

remain

operations until the module is reset.

Revision C silicon will correct this issue.

Work around

Do not selectively clear bit CCPxM0 to select the

Compare/Set on Match mode. Instead, clear the

entire CCPxCON register, which resets the mod-

ule. Follow this with an instruction to set CCPxM3

(CCPxCON<3>), which selects the Set on Match

mode.
