Bit
Mnemonic
Default
Description
7
SMOD
0
Double baud rate control.
[6:0]
Reserved
0

Table 59. Data Pointer Low SFR (DPL, Address 0x82)
Bit
Mnemonic
Default
Description
[7:0]
DPL
0
These bits contain the low byte of the data pointer.
Table 60. Data Pointer High SFR (DPH, Address 0x83)
Bit
Mnemonic
Default
Description
[7:0]
DPH
0
These bits contain the high byte of the data pointer.

Bit
Mnemonic
Default
Description
7
Reserved
1
Reserved. This bit should be left set for proper operation.
6
EXTEN
0
Enhanced UART enable bit.
EXTEN
Result

Features section).
5
SCPS
0
Synchronous communication selection bit.
SCPS
Result
0
I2C port is selected for control of the shared I2C/SPI pins and SFRs.
1
SPI port is selected for control of the shared I2C/SPI pins and SFRs.
4
MOD38EN
0
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, Address 0x9F).
[3:2]
Reserved
00
Reserved. These bits should be kept at 0 for proper operation.
[1:0]
XREN1, XREN0
01
XREN[1:0]
Result
XREN1 OR XREN0 = 1
Enable MOVX instruction to use 256 bytes of extended RAM.
XREN1 AND XREN0 = 0
Disable MOVX instruction.
