0
Description
SMOD bit. Double baud rate control.
Reserved. Should be left cleared.
Bits
15 to 0
Default
0
Description
Contain two byte address of the data
pointer. DPTR is the combination of DPH
and DPL SFRs.

Table 58. Stack Pointer SFR (SP, 0x81)
Bits
7 to 0
Default
0
Description
Contain the low byte of the data pointer.
Bits
7 to 0
Default
7
Description
Contain the 8 LSBs of the pointer for the stack.
Table 56. Data Pointer High SFR (DPH, 0x83)
Bits
7 to 0
Default
0
Description
Contain the high byte of the data pointer.

Description
This bit should be left set for proper operation.
Enhanced UART Enable Bit.
EXTEN Result
0 Standard 8052 UART without enhanced error-checking features.
1 Enhanced UART with enhanced error checking (see the UART Additional Features section).
Synchronous Communication Selection Bit.
SCPS Result
0 I 2 C port is selected for control of the shared I 2 C/SPI pins and SFRs.
1 SPI port is selected for control of the shared I 2 C/SPI pins and SFRs.
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).
