Table 1-4. Versions of On-Chip Modules
Serial communications UARTs capable of supporting RS-232 and LIN
protocols
SPI1 has full-complementary drive outputs. SPI2 may be configured
with full-complementary drive output via LCD control registers. SPI3
has open drain outputs on SCLK and (MISO or MOSI). These coupled
with off-chip pullup resistors, allow interface to an external 5V SPI.
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 in separate
power domains.One is intended primarily for use by the IRTC, and the
other by the CPU and other peripherals.
