NAME
tcic - Databook TCIC-2 PCMCIA controller driver
SYNOPSIS
insmod tcic.o [pc_debug=n] [tcic_base=n] [ignore=n] [do_scan=n] [irq_list=i,j,...] [cs_irq=n] [poll_inter val=n] [poll_quick=n] [cycle_time=n]
DESCRIPTION
This is the low-level driver for the Databook TCIC-2 PCM
CIA host controller family. It is used by Card Services
for programming the TCIC-2 chip, and for monitoring card
status change events.
PARAMETERS
- pc_debug=n
- Selects the PCMCIA debugging level. This parameter
is only available if the module is compiled with
debugging enabled. A non-zero value enables debug
ging. - tcic_base=n
- Sets the base I/O port address of the TCIC-2 chip.
The default is 0x240. - ignore=n
- Causes the driver to ignore a single socket. Sock
ets are numbered starting at 0. The socket will be
left in whatever state it was already in, so it can
be used for cards with point enablers that do not
cooperate with Card Services. - do_scan=n
- This flag specifies that all free interrupts should
be tested to see if they can be triggered by the
PCMCIA controller. The default is 1 (on). - irq_list=i,j,...
- Specifies the set of interrupts that may be allo
cated by this driver, if they are otherwise avail
able. The default list is 3, 4, 5, 6, 7, 10, 11,
and 14. - cs_irq=n
- Sets the interrupt line to use for monitoring card
status changes. The default is 0, which means pick
any legal interrupt not already in use. Legal val
ues are 14, 10, 7, 6, 5, 4, and 3. - poll_interval=n
- Sets the card status polling delay, in 1/100 second
increments. If this parameter is set, card status
interrupts will be disabled. - poll_quick=n
- When a card status change interrupt is received,
the TCIC-2 chip is briefly polled for additional
status changes. This parameter sets the polling
delay, in 1/100 second increments. The default is
5, meaning 0.05 seconds. - cycle_time=n
- Sets the length of a CCLK external clock cycle, in
nanoseconds. The default is 70 ns, corresponding
to a standard ISA 14.31818 MHz clock.
