Result
Standard 8052 UART without enhanced error-checking features.
Enhanced UART with enhanced error checking (see the UART Additional Features section).
Result
I
SPI port is selected for control of the shared I
Result
38 kHz modulation is disabled.
38 kHz modulation is enabled on the pins selected by the MOD38[7:0] bits in the
Extended Port Configuration SFR (EPCFG, 0x9F).
Result
Enables MOVX instruction to use 256 bytes of extended RAM.
