Serial transfers of eight to 16 bits can be specified. Programmable transfer length simplifies interfacing to
devices that require different data lengths.
An inter-transfer delay of approximately 0.8 to 204 µs (using a 40-MHz IMB3 clock) can be programmed.
The default delay is 17 clocks (0.425 µs at 40 MHz). Programmable delay simplifies the interface to
devices that require different delays between transfers.
