C interrupt priority level.
If IP.5 = 1, the priority level is higher.
IP.4
PS
Define the serial port interrupt priority level.
If PS = 1, the priority level is higher.
IP.3
PT1
Define the Timer 1 interrupt priority level.
If PT1 = 1, the priority level is higher.
IP.2
*1
Define the *2 priority level.
If IP.2 = 1, the priority level is higher.
IP.1
PT0
Define the Timer 0 interrupt priority level.
If PT0 = 1, the priority level is higher.
IP.0
PX0
Define the external interrupt 0 priority level.
If PX0 = 1, the priority level is higher.
Notes:
*1. No name for ASSEMBLER, must be used via "IP.x".
*2. DSCLINT+ADCINT+TIMEOUT+SOAINT+VEVENT+PARAINT+DDC1INT.
C. Newly Added Special Function Registers
In addition to the 80C32 SFRs, the W78C354 has forty-nine new SFRs in the SFR address space, as
