PIICR: Undefined Instruction Interrupt Control Register
Bit: 7 6 5 4
— — — —
Reset: 0 0 0 0
R/W: R R R R
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
Bit: 7 6 5 4
— — — —
Reset: 0 0 0 0
R/W: R R R R
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)
Bit: 7 6 5 4
— — — IQ0IR
Reset: 0 0 0 0
R/W: R R R R/W
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
