Enhanced UART with enhanced error checking (see the UART Additional Features section).
Synchronous Communication Selection Bit.
SCPS Result
I 2 C port is selected for control of the shared I 2 C/SPI pins (MOSI, MISO, SCLK, and SS ) and SFRs.
0
SPI port is selected for control of the shared I 2 C/SPI pins (MOSI, MISO, SCLK, and SS) and SFRs.
1
38 kHz Modulation Enable Bit.
MOD38EN Result
0
38 kHz modulation is disabled.
1
38 kHz modulation is enabled on the pins selected by the MOD38[7:0] bits in the
Extended Port Configuration SFR (EPCFG, 0x9F).
