Architectural Overview
â Power and ground for the analog circuitry is separate from the digital power and ground
â UART
â Two fully programmable 16C550-type UARTs with IrDA support
â Separate 16x8 transmit (TX) and receive (RX) FIFOs to reduce CPU interrupt service loading
â Programmable baud-rate generator allowing speeds up to 3.125 Mbps
â Programmable FIFO length, including 1-byte deep operation providing conventional
double-buffered interface
â FIFO trigger levels of 1/8, 1/4, 1/2, 3/4, and 7/8
â Standard asynchronous communication bits for start, stop, and parity
â Line-break generation and detection
â Fully programmable serial interface characteristics
⢠5, 6, 7, or 8 data bits
⢠Even, odd, stick, or no-parity bit generation/detection
⢠1 or 2 stop bit generation
â IrDA serial-IR (SIR) encoder/decoder providing
⢠Programmable use of IrDA Serial Infrared (SIR) or UART input/output
⢠Support of IrDA SIR encoder/decoder functions for data rates up to 115.2 Kbps half-duplex
⢠Support of normal 3/16 and low-power (1.41-2.23 μs) bit durations
⢠Programmable internal clock generator enabling division of reference clock by 1 to 256
for low-power mode bit duration
â Synchronous Serial Interface (SSI)
â Two SSI modules, each with the following features:
â Master or slave operation
â Programmable clock bit rate and prescale
â Separate transmit and receive FIFOs, 16 bits wide, 8 locations deep
â Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
â Programmable data frame size from 4 to 16 bits
â Internal loopback test mode for diagnostic/debug testing
â I2C
