M68HC16 Z SERIES
USER’S MANUAL
This section is an overview of the multichannel communication interface (MCCI) mod-
ule. Refer to the MCCI Reference Manual (MCCIRM/AD) for more information on
MCCI capabilities. Refer to
MCCI timing and electrical specifications. Refer to
Interface Module
The MCCI contains three serial interfaces: a serial peripheral interface (SPI) and two
serial communication interfaces (SCI).
The MCCI is present only on MC68HC16Z4 and MC68CK16Z4 microcontrollers.
The SPI provides easy peripheral expansion or interprocessor communication via a
full-duplex, synchronous, three-line bus: data in, data out, and a serial clock. Serial
transfer of eight or sixteen bits can begin with the most significant bit (MSB) or least
significant bit (LSB). The MCCI module can be configured as a master or slave device.
Clock control logic allows a selection of clock polarity and a choice of two clocking pro-
tocols to accommodate most available synchronous serial peripheral devices. When
the SPI is configured as a master, software selects one of 254 different bit rates for the
serial clock.
