Motorola Master Selection Guide
Single-Chip Microcontrollers (AMCU)
2.6–13
Timer Module (TM)
16–bit free–running counter with 8–bit prescaler
Two TM can be externally cascaded to increase
count width
Software selected input capture,
output compare,
pulse accumulation, event counting, or pulse–width
modulation functions
Communication Modules
Queued Serial Module (QSM)
Queued full–duplex, synchronous three–line SPI with
dedicated RAM
Standard, asynchronous NRZ–format SCI
Polled and interrupt–driven operation
Pins can be configured as a parallel I/O port
Multi–Channel Communications Interface
(MCCI)
One full–duplex synchronous three–line SPI
Two independent standard, asynchronous NRZ–format SCI
Polled and interrupt–driven operation
Pins can be configured as a parallel I/O port
Dual Universal Asynchronous/
Synchronous Receiver Transmitter (DUART)
Dual NRZ Serial RS–232C channels
Independently programmable TxD and Receiver
Transmitter (DUART)
