Symbol
Function
EXTRAM
Internal/External RAM access
0: Internal Expanded RAM access within range of 00H to FFH using MOVX @Ri /
@DPTR. Beyond 100H, the MCU always accesses external data memory.
For details, refer to Section 3.3, “Expanded Data RAM Addressing” .
1: External data memory access.
AO
Disable/Enable ALE
0: ALE is emitted at a constant rate of 1/3 the oscillator frequency in 6 clock mode, 1/6 fOSC in
12 clock mode.
1: ALE is active only during a MOVX or MOVC instruction.
Symbol
Function
GF2
General purpose user-defined flag
DPS
DPTR registers select bit
0: DPTR0 is selected.
1: DPTR1 is selected.
Symbol
Function
SFIS0
Register used with SFIS1 to provide a feed sequence to validate writing
to WDTC and SFCM. Without a proper feed sequence, writing to SFCM will be ignored
and writing to WDTC in Watchdog mode will cause an immediate Watchdog reset.
