Enhanced Serial Communications Interface (ESCI) Module
RPF — Reception in Progress Flag Bit
14.8.6 ESCI Data Register
The ESCI data register (SCDR) is the buffer between the internal data bus and the receive and transmit
shift registers. Reset has no effect on data in the ESCI data register.
R7/T7:R0/T0 — Receive/Transmit Data Bits
14.8.7 ESCI Baud Rate Register
The ESCI baud rate register (SCBR) together with the ESCI prescaler register selects the baud rate for
both the receiver and the transmitter.
LINT — LIN Transmit Enable
212
This read-only bit is set when the receiver detects a 0 during the RT1 time period of the start bit search.
RPF does not generate an interrupt request. RPF is reset after the receiver detects false start bits
(usually from noise or a baud rate mismatch), or when the receiver detects an idle character. Polling
RPF before disabling the ESCI module or entering stop mode can show whether a reception is in
progress.
Reading address $0018 accesses the read-only received data bits, R7:R0. Writing to address $0018
writes the data to be transmitted, T7:T0. Reset has no effect on the ESCI data register.
This read/write bit selects the enhanced ESCI features for the local interconnect network (LIN) protocol
as shown in
1 = Reception in progress
0 = No reception in progress
Address:
Address:
Do not use read-modify-write instructions on the ESCI data register.
There are two prescalers available to adjust the baud rate. One in the ESCI
baud rate register and one in the ESCI prescaler register.
