Table 127. Input Slot 1 Bit Definitions
Input Slot 2: Status Data Port
Input Slot 4: PCM Record Right Channel
Input Slot 5: Modem Line
NOTES:
As shown in
slot request flags for all output slots of the controller. When a slot request bit is set by the codec, the
controller returns data in that slot in the next output frame. Slot request bits for slots 3 and 4 are
always set or cleared in tandem (i.e., both are set or cleared).
When set, the input slot 1 tag bit only pertains to Status Address Port data from a previous read.
SLOTREQ bits are always valid independent of the slot 1 tag bit.
The status data port receives 16-bit control register read data.
Bit [19:4]: Control Register Read Data
Bit [3:0]:
Input slot 3 is the left channel input of the codec. The ICH5 supports 16-bit sample resolution.
Samples transmitted to the ICH5 must be in left/right channel order.
Input slot 4 is the right channel input of the codec. The ICH5 supports 16-bit sample resolution.
Samples transmitted to the ICH5 must be in left/right channel order.
Input slot 5 contains MSB justified modem data. The ICH5 supports 16-bit sample resolution.
1. Slot 3 Request and Slot 4 Request bits must be the same value, i.e. set or cleared in tandem. This is also true
18:12
for the Slot 7 and Slot 8 Request bits, as well as the Slot 6 and Slot 9 Request bits.
