Special Instructions Section 5-26
Set the corresponding bit in D to 0 or 1 to unmask or mask an I/O interrupt
input. Bits 00 to 03 correspond to 00000 to 00003 (00003 to 00006 in CPM1/
CPM1A PCs). Bits 04 to 15 should be set to 0.
Clear I/O Interrupts
(CC=001)
This function is used to clear I/O interrupt inputs 00000 to 00003 (00003 to
00006 in CPM1/CPM1A PCs). Since interrupt inputs are recorded, masked
interrupts will be serviced after the mask is removed unless they are cleared
first.
Set the corresponding bit in D to 1 to clear an I/O interrupt input. Bits 00 to 03
correspond to 00000 to 00003 (00003 to 00006 in CPM1/CPM1A PCs). Bits
04 to 15 should be set to 0.
Read Current Mask Status
(CC=002)
This function is used to write the current mask status for I/O interrupt inputs
00000 to 00003 (00003 to 00006 in CPM1/CPM1A PCs) to word D. The corre-
sponding bit will be ON if the input is masked. (Bits 00 to 03 correspond to
00000 to 00003 in CQM1 PCs, 00003 to 00006 in CPM1/CPM1A PCs.)
Renew Counter SV
(CC=003)
This function is used to renew the counter SV for I/O interrupt inputs 00000 to
00003 (00003 to 00006 in CPM1/CPM1A PCs) to word D. Set the correspond-
Interrupt input 00000 (0: unmask, 1: mask)
Interrupt input 00001 (0: unmask, 1: mask)
Interrupt input 00002 (0: unmask, 1: mask)
Interrupt input 00003 (0: unmask, 1: mask)
Word D bits: 3 2 1 0
CQM1 PCs
Interrupt input 00003 (0: unmask, 1: mask)
Interrupt input 00004 (0: unmask, 1: mask)
Interrupt input 00005 (0: unmask, 1: mask)
Interrupt input 00006 (0: unmask, 1: mask)
Word D bits: 3 2 1 0
CPM1/CPM1A PCs
Interrupt input 00000 (0: Do not clear, 1: clear)
Interrupt input 00001 (0: Do not clear, 1: clear)
Interrupt input 00002 (0: Do not clear, 1: clear)
Interrupt input 00003 (0: Do not clear, 1: clear)
Word D bits: 3 2 1 0
CQM1 PCs
Word D bits: 3 2 1 0
CPM1/CPM1A PCs
Interrupt input 00003 (0: Do not clear, 1: clear)
Interrupt input 00004 (0: Do not clear, 1: clear)
Interrupt input 00005 (0: Do not clear, 1: clear)
Interrupt input 00006 (0: Do not clear, 1: clear)
Interrupt input 00000 (0: not masked, 1: masked)
Interrupt input 00001 (0: not masked, 1: masked)
Interrupt input 00002 (0: not masked, 1: masked)
Interrupt input 00003 (0: not masked, 1: masked)
Word D bits: 3 2 1 0
CQM1 PCs
Word D bits: 3 2 1 0
CPM1/CPM1A PCs
Interrupt input 00003 (0: not masked, 1: masked)
Interrupt input 00004 (0: not masked, 1: masked)
Interrupt input 00005 (0: not masked, 1: masked)
Interrupt input 00006 (0: not masked, 1: masked)
