In order to use this module, other parts of the system must be configured correctly, as described
below.
The ACIFB pins are multiplexed with other peripherals. The user must first program the I/O Con-
troller to give control of the pins to the ACIFB.
If the CPU enters a sleep mode that disables clocks used by the ACIFB, the ACIFB will stop
functioning and resume operation after the system wakes up from sleep mode.
