Description
Data pointer low byte
This is the low byte of 16-bit data pointer. DPL combined with DPH serve as a 16-
bit data pointer DPTR to access indirect addressed RAM or Program Memory.
DPS (AUXR1.0) bit decides which data pointer, DPTR or DPTR1, is activated.

Description
Serial port 0 double baud rate enable
Setting this bit doubles the serial port baud rate when UART0 is in Mode 2 or
when Timer 1 overflow is used as the baud rate source of UART0 Mode 1 or 3.
See Table 13-1. Serial Port 0 Mode Description for details.
Serial port 0 framing error flag access enable
0 = SCON.7 accesses to SM0 bit.
1 = SCON.7 accesses to FE bit.
