Table 2. MCF51MM256/128 Functional Units (continued)
Serial communications UARTs capable of supporting RS-232 and LIN
protocols.
SPI1 and SPI2 provide standard master/slave capability. SPI contains a
FIFO buffer in order to increase the throughput for this peripheral.
Timer/PWM module can be used for a variety of generic timer
operations as well as pulse-width modulation.
Controls power management across the device.
These devices incorporate redundant crystal oscillators. One is
intended primarily for use by the TOD, and the other by the CPU and
other peripherals.
