Transmit Async Control Character Map 2 (TXACCM2)
Transmit Async Control Character Map 3 (TXACCM3)
The TXACCM registers define transmitted characters in the range 00–1F as mapped (Control bit
set) or not mapped (Control bit clear) as follows:
TXACCM0 bits 0–7 control characters 00–07, respectively.
TXACCM1 bits 0–7 control characters 08–0F, respectively.
TXACCM2 bits 0–7 control characters 10–17, respectively.
TXACCM3 bits 0–7 control characters 18–1F, respectively.
