31.5 Functional Description

The RXLP features an RS232 receive-only circuitry able to decode and compare data and parity while the system is in Backup mode. If a matching comparison occurs, the RXLP instructs the system to wake up (if enabled).

The RXLP operates in Asynchronous mode only and supports only 8-bit character handling (with or without parity).

The RXLP is made up of a receiver and a baud rate generator. Receiver timeout is not implemented and there is no interrupt line.
