Function
Internal/External RAM access
0: Internal Expanded RAM access within range of 00H to 2FFH using MOVX @Ri /
@DPTR. Beyond 300H, the MCU always accesses external data memory.
For details, refer to Section 3.4, “Expanded Data RAM Addressing” .
1: External data memory access.
Disable/Enable ALE
0: ALE is emitted at a constant rate of 1/3 the oscillator frequency in 6 clock mode, 1/6 f
12 clock mode.
1: ALE is active only during a MOVX or MOVC instruction.
6
Function
General purpose user-defined flag.
DPTR registers select bit.
0: DPTR0 is selected.
1: DPTR1 is selected.
6
Function
Watchdog output enable.
0: Watchdog reset will not be exported on Reset pin.
1: Watchdog reset if enabled by WDRE, will assert Reset pin for 32 clocks.
Watchdog timer reset enable.
0: Disable watchdog timer reset.
1: Enable watchdog timer reset.
Watchdog timer reset flag.
0: External hardware reset or power-on reset clears the flag.
1: Hardware sets the flag on watchdog overflow.
Watchdog timer refresh.
0: Hardware resets the bit when refresh is done.
1: Software sets the bit to force a watchdog timer refresh.
Start watchdog timer.
0: Stop WDT.
1: Start WDT.

Flag can also be cleared by writing a 1.
Flag survives if chip reset happened because of watchdog timer overflow.
