•
32-bit down counter with a programmable load register
Separate watchdog clock with an enable
Programmable interrupt generation logic with interrupt masking
Lock register protection from runaway software
Reset generation logic with an enable/disable
User-enabled stalling when the controller asserts the CPU Halt flag during debug
Supports CAN protocol version 2.0 part A/B
Bit rates up to 1Mb/s
32 message objects, each with its own identifier mask
Maskable interrupt
Disable automatic retransmission mode for TTCAN
Programmable loop-back mode for self-test operation
Master or slave operation
Programmable clock bit rate and prescale
Separate transmit and receive FIFOs, 16 bits wide, 8 locations deep
Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
Programmable data frame size from 4 to 16 bits
Internal loopback test mode for diagnostic/debug testing
Direct memory access (DMA)
Two fully programmable 16C550-type UARTs with IrDA support
Separate 16x8 transmit (TX) and 16x12 receive (RX) FIFOs to reduce CPU interrupt service
loading
Programmable baud-rate generator allowing speeds up to 3.125 Mbps
Simple PWM mode with software-programmable output inversion of the PWM signal
