FO - FEVTR
Reset Value: 0xxxxxxxxxxxxxxx
This bit is used for CardBus purposes.
15 - FEVTR: This function event register bit is
a register for holding interrupts in the CardBus
environment.
14 through 0 - unused.
F4 - FEVTRMSKR
Reset Value: 0xxxxxxxxxxxxxxx
This bit is the mask for the fevtr bit in CardBus
operations.
15 - FEVTRMSKR: This bit is used for holding
the mask for the fevtr interrupt. If it is ‘1’, an
interrupt derived from fevtr will not go out to
the host.
14 through 0 - unused.
F8 - FPRSTSTR
Reset Value: 01
This register is the function present register for
CardBus operations.
1 - FPRST_INT: This bit reflects the interrupt
status before it has been sent to the function
event register.
0 - The CardBus bus functions are always
present, and this will always return a ‘1.’ It
cannot be written.
FC - FFRCEVTR
Reset Value: 0
This register is the function force event register for
CardBus operations.
15 - FFRCEVTR: When this bit is written to, the
fevtr register will become ‘1’.
14 through 0 - unused.
FC - CardBus TRANSMIT DMA TEST
Reset Value: 00
This register is used for test and should never be
accessed during normal operation.
31 through 2 - Reserved for test functions.
1 and 0 - TBD.
