The n is the IXPCI device number.

ioctl Commands

IXPCI_GET_INFO

Retrieve a device's information, and put it into the ixpci_devinfo (ixpci_devinfo_t) structure. Example: list.c.

IXPCI_READ_REG

Read a specified register's value, and put the value into the ixpci_reg (ixpci_reg_t) structure. Example: ixpcitmc12/dio.c

IXPCI_WRITE_REG

Write a given value to a specified register. Example: ixpcitmc12/dio.c

IXPCI_SET_SIG

Set interrupt signaling condition. Example: pcitmc12/int.c

IXPCI_IOCTL_DI

Digital input. Example: pcitmc12/dio2.c

IXPCI_IOCTL_DO

Digital output. Example: pcitmc12/dio2.c

IXPCI_RESET

Reset device.

• Stop all timers
• Write 0 to DO.
• Disable interrupt

Example: ixpcitmc12/rst.c
