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] [async_clock=n]

DESCRIPTION
       This  is the low-level driver for the Databook TCIC-2 PCM-
       CIA interface controller.  It is used by Card Services for
       programming  the TCIC-2 chip, and for monitoring card sta-
       tus 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.

       async_clock=n
              This flag specifies that PCMCIA bus  cycles  should
              be  clocked  asynchronously  from  host bus cycles,
              effectively adding extra wait states to some opera-
              tions.  The default is 0 (off).
