Description
Not used
Port 1 peripheral priority control. These bits shall determine the
order of priority in the case when PERCFG assigns USART0 and
USART1 to the same pins.
0 USART0 has priority
1 USART1 has priority
Port 1 peripheral priority control. These bits shall determine the
order of priority in the case when PERCFG assigns USART1 and
timer 3 to the same pins.
0 USART1 has priority
1 Timer 3 has priority
Port 1 peripheral priority control. These bits shall determine the
order of priority in the case when PERCFG assigns timer 1 and
timer 4 to the same pins.
