access using MOVX @ Ri/@ DPTR
0 - Internal XRAM access using MOVX @ Ri/@ DPTR.
1 - External data memory access.
Disable/Enable ALE)
0 - ALE is emitted at a constant rate of 1/6 the oscillator frequency (or 1/3 if X2
mode is used)
1 - ALE is active only during a MOVX or MOVC instruction.
Reserved
The value read from these bits is indeterminate. Do not set these bits.
Enable Boot Flash
Set this bit for map the boot Flash between F800h -FFFFh
Clear this bit for disable boot Flash.
Reserved
The value read from this bit is indeterminate. Do not set this bit.
General-purpose Flag 3
Always Zero
This bit is stuck to logic 0 to allow INC AUXR1 instruction without affecting GF3
flag.
Reserved for Data Pointer Extension.
Data Pointer Select Bit
Set to select second dual data pointer: DPTR1.
Clear to select first dual data pointer: DPTR0.
