(ii) Initialization Command Word 3 (ICW3)
This command word is written when there is more than one MSM82C59A-2 used in
cascade connections in the system, and is loaded into an 8-bit slave register. The
functions of this slave register are listed below.
a. In a master mode system (BUF = 1 and M/ S = 1 in ICW4 or SP/EN = 1). “1” is set
in each bit where a slave has been connected.
In 85 mode, the master MSM82C59A-2 releases byte 1 of the CALL sequence to
enable the corresponding slave to release byte 2 or 3 (only byte 2 in 86 mode) through
the cascade line.
b. In slave mode (BUF = 1 and M/S = 0 in ICW4 or SP/EN = 0). Bits 0 thru 2 identify
the slave. The slave compares these bits with the cascade input, and releases bytes
2 and 3 of the CALL sequence (only byte 2 in 86 mode) if a matching result is obtained.
(iii) Initialization Command Word 4 (ICW4)
SFNM: Special Fully Nested Mode is programmed when SFNM = 1.
BUF:
Buffered mode is programmed when BUF = 1. In Buffered mode, SP/EN is an
output, and Master/slave is selected by the M/S bit.
M/S:
If buffered mode is selected, the MSM82C59A-2 is programmed as the master
when M/S = 1, and as a slave when M/S = 0. M/S is ignored, however, when
BUF = 0.
AEOI: Automatic End Of Interrupt mode is programmed by AEOI = 1.
mPM:
(Microprocessor mode)
The MSM82C59A-2 is set to 85 system operation when mPM = 0, and to 86
system operation when mPM = 1.
