MPC555
USER’S MANUAL
Serial transfers of eight to 16 bits can be specified. Programmable transfer length sim-
plifies interfacing to devices that require different data lengths.
An inter-transfer delay of approximately 0.8 to 204 µs (using a 40-MHz IMB 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.
