INT_PEND1

INT_PEND1	Address:	0012H
	Reset State:	00H

When hardware detects a pending interrupt, it sets the corresponding bit in the interrupt pending (INT_PEND or INT_PEND1) registers. When the vector is taken, the hardware clears the pending bit. Software can generate an interrupt by setting the corresponding interrupt pending bit.

	The standard interrupt vector locations are as follows:
	Bit Mnemonic	Interrupt	Standard Vector
	NMI	Nonmaskable Interrupt	203EH
	EXTINT	EXTINT pin	203CH
	PI (MC, MD)††	Multiplexed Peripheral Interrupt	203AH
	WG (MH)	Waveform Generator	203AH
	EPA5 (MD)	EPA Capture/Compare Channel 5	2038H
	SPI (MH)†††	Serial Port	2038H
	COMP4 (MD)	EPA Compare Channel 4	2036H
	RI1 (MH)	SIO 1 Receive	2036H
	EPA4 (MD)	EPA Capture/Compare Channel 4	2034H
	RI0 (MH)	SIO 0 Receive	2034H
	COMP3 (MC, MD)	EPA Compare Channel 3	2032H
	TI1 (MH)	SIO 1 Transmit	2032H
	EPA3 (MC, MD)	EPA Capture/Compare Channel 3	2030H
	TI0 (MH)	SIO 0 Transmit	2030H

††On the 8XC196MD, the waveform generator and the EPA compare channel 5 can generate this interrupt. Write to PI_MASK to enable the interrupt sources; read PI_PEND to determine which source caused the interrupt. On the 8XC196MC, the waveform generator is the sole source for this interrupt.

†††SIO 0 and SIO 1 can generate this interrupt. Write to PI_MASK to enable the interrupt sources; read PI_PEND to determine which source caused the interrupt.

†On the 8XC196MC device bits 4–3 are reserved. These bits are undefined.
