3.6.12 TSC_1X22_MAFE_IRQ_SW
Description
This IOCTL enables the use of a SW based interrupt scheme for the 73M1x22 device to be reported
through the HW Module. Auto polling (see TSC_1X22_MAFE_SET_REG_AUTO_POLL) must be enabled
for register 0x03 for this feature to work properly. The interrupt mutex/enables remains in their current
state after this call.
