EXAMPLE 4:
2001 Microchip Technology Inc.
The Timer1 value may unexpectedly increment if
either the TMR1H, or the TMR1L register is writ-
ten. If Timer1 is ON and then turned OFF, perform-
ing any write instruction with TMR1H as the
destination, may cause TMR1L to increment.
If Timer1 is ON and then turned OFF when
TMR1H:TMR1L = xx:FF, performing any write
instruction with TMR1L as the destination may
cause TMR1H to increment.
Work around
To preserve Timer1 register values:
a) Read Timer1 register values into “shadow”
b) Perform any write instruction(s) on the
c) Write the shadow register values back into

8. Module: USART
When the USART (SCI) is configured in Asynchro-
nous mode with the BRGH bit set, a high number
of receive errors may be experienced. For asyn-
chronous receive operations, it is recommended
that the USART be configured with the BRGH bit
cleared.
