* Driver: addi_apci_1564
* Description: ADDI-DATA APCI-1564 Digital I/O board
* Devices: [ADDI-DATA] APCI-1564 (addi_apci_1564)
* Author: H Hartley Sweeten <[email protected]>
* Updated: Thu, 02 Jun 2016 13:12:46 -0700
* Status: untested
*
* Configuration Options: not applicable, uses comedi PCI auto config
*
* This board has the following features:
* - 32 optically isolated digital inputs (24V), 16 of which can
* generate change-of-state (COS) interrupts (channels 4 to 19)
* - 32 optically isolated digital outputs (10V to 36V)
* - 1 8-bit watchdog for resetting the outputs
* - 1 12-bit timer
* - 3 32-bit counters
* - 2 diagnostic inputs
*
* The COS, timer, and counter subdevices all use the dev->read_subdev to
* return the interrupt status. The sample data is updated and returned when
* any of these subdevices generate an interrupt. The sample data format is:
*
* Bit Description
* ----- ------------------------------------------
* 31 COS interrupt
* 30 timer interrupt
* 29 counter 2 interrupt
* 28 counter 1 interrupt
* 27 counter 0 interrupt
* 26:20 not used
* 19:4 COS digital input state (channels 19 to 4)
* 3:0 not used
*
* The COS interrupts must be configured using an INSN_CONFIG_DIGITAL_TRIG
* instruction before they can be enabled by an async command. The COS
* interrupts will stay active until canceled.
*
* The timer subdevice does not use an async command. All control is handled
* by the (*insn_config).
*
* FIXME: The format of the ADDI_TCW_TIMEBASE_REG is not descibed in the
* datasheet I have. The INSN_CONFIG_SET_CLOCK_SRC currently just writes
* the raw data[1] to this register along with the raw data[2] value to the
* ADDI_TCW_RELOAD_REG. If anyone tests this and can determine the actual
* timebase/reload operation please let me know.
*
* The counter subdevice also does not use an async command. All control is
* handled by the (*insn_config).
*
* FIXME: The operation of the counters is not really described in the
* datasheet I have. The (*insn_config) needs more work.
