: DMA Mode Enable Bit.
: PCMCIA Interface Disable Bit.
If this bit is set to “1”, signals shown in the below table are set to “Z”, all PCMCIA interface signals are
disabled and become “Z”. The built-in pull-down resistor is disabled for data bus signals. Slot output sig-
nals will be caused to transition to high impedance even when bit 0 is set in the Power and RESETDRV
Control Register.
When this bit is set to “1”, the DMA Mode is selected in which DMA-related signals are redefined as
described in “DMA Mode”. This bit defaults to “0”. This bit cannot be set to “1” simultaneously for
Slot #0 and Slot #1.
Default value : 0000 0000b
Default value : 0000 0000b
Default value : 32h (RF5C296), B2h (RF5C396)
Read only register, 32h is read back from RF5C296, B2h is read back from RF5C396.
