PIICR: Undefined Instruction Interrupt Control Register x’00FC44’
PIICR is an 8-bit access register.
PIID: Undefined instruction interrupt detect flag
0: Interrupt undetected
1: Interrupt detected
EIICR: Interrupt error Interrupt Control Register x’00FC46’
EIICR does not exist in the hardware, but if the CPU finds no matching
interrupt vector for an interrupt that occurs, it writes a C to IAGR to indi-
cate that it detected an abnormality. EIICR is an 8-bit access register.
IQ0ICL: External Interrupt 0 Interrupt Control Register (Low) x’00FC48’
IQ0ICL requests and verifies interrupt requests for external interrupt 0. It
is an 8-bit access register. Use the MOVB instruction to access it.
IQ0IR: External interrupt 0 interrupt request flag
0: No interrupt requested
1: Interrupt requested
IQ0ID: External interrupt 0 interrupt detect flag
0: Interrupt undetected
1: Interrupt detected
