CHAPTER 3 INTERRUPTS

[bit 15 to bit 12, bit 7 to bit 4] ICS 3 to ICS 0 (extended intelligent I/O service channel select bits)

ICS3 to ICS0 are write-only bits. These bits specify the EI

2

OS channel. The values set in these bits

determined the extended intelligent I/O service descriptor addresses in memory, which is explained

later. The ICS bits are initialized to "0000

B

" by a reset.

Table 3.3-2 describes the correspondence between the ICS bits, channel numbers, and descriptor

addresses.
