Priority interrupt circuit control bit.
The priority register contents are valid and priority assigned interrupts can be
processed when this bit is "0". When the bit is "1", the priority interrupt circuit is
stopped, and interrupts can only be controlled by the interrupt enable register (IE).
IP.7
PCT
Interrupt priority bit for timer interrupt 0.
Priority is assigned when bit is "1".
Interrupt priority bit for external interrupt 1.
Priority is assigned when bit is "1".
Interrupt priority bit for timer interrupt 1.
Priority is assigned when bit is "1".
Interrupt priority bit for serial port.
Priority is assigned when bit is "1".
Interrupt priority bit for timer interrupt 2.
Priority is assigned when bit is "1".
Interrupt priority register (IP)
