Infrared Serial Communications Interface Module (IRSCI)
13.3 Features
Features of the SCI module include the following:
⢠Full duplex operation
⢠Standard mark/space non-return-to-zero (NRZ) format
⢠Programmable 8-bit or 9-bit character length
⢠Separately enabled transmitter and receiver
⢠Separate receiver and transmitter CPU interrupt requests
⢠Two receiver wakeup methods:
â Idle line wakeup
â Address mark wakeup
⢠Interrupt-driven operation with eight interrupt flags:
â Transmitter empty
â Transmission complete
â Receiver full
â Idle receiver input
â Receiver overrun
â Noise error
â Framing error
â Parity error
⢠Receiver framing error detection
⢠Hardware parity checking
⢠1/16 bit-time noise detection
Features of the infrared (IR) sub-module include the following:
⢠IR sub-module enable/disable for infrared SCI or conventional SCI
on TxD and RxD pins
⢠Software selectable infrared modulation/demodulation
(3/16, 1/16 or 1/32 width pulses)
