Description
When set to 1, this bit activates PDIAG on the PCMCIA
bus side. On Power-On Reset, this bit is set to 0.
When set to 1, this bit drives the PCMCIA pin on the
PCMCIA side. On Power-On Reset, this bit is set to 0
(Table 15). Also see Registers 04h, 07h.
When set to 1, this bit sets the DASP pin on the PCMCIA
side. On Power-On Reset, this bit is set to 0.
When set to 1, this bit drives the DASP pin on the
PCMCIA side. On Power-On Reset, this bit is set to 0
(Table 16).
When set to 1, this bit is active and ATA_HCS0 has the
same level as ATA_HCS1. On Power-On Reset, this bit is
set to 0 (Table 17). Also see Register 03h (Table 19).
When set to 1, this bit is active and connects
EXTP_AUDIO (inverted) to the PC_BVD2//SPKR//
DASP/DREQ pin. On Power-On Reset, this bit is set to 0
(Table 18).
When set to 1, DASP is generated internally. On Power-On
Reset, this bit is set to 0.
When set to 1, DASP is generated externally from the
AT_DASP pin on the local AT bus side. On Power-On
Reset, this bit is set to 0. Also see Register 01h (Table 13).
