Description
Disable Weak Pull Up
Cleared to enabled weak pull up on standard Ports.
Set to disable weak pull up on standard Ports.
Reserved
The value read from this bit is indeterminate. Do not set this bit
Pulse length
Cleared to stretch MOVX control: the RD and the WR pulse length is 6 clock
periods (default).
Set to stretch MOVX control: the RD and the WR pulse length is 30 clock
periods.

EXTRAM bit
Cleared to access internal ERAM using MOVX at Ri at DPTR.
Set to access external memory.
ALE Output bit
Cleared, ALE is emitted at a constant rate of 1/6 the oscillator frequency (or
1/3 if X2 mode is used) (default).
Set, ALE is active only when a MOVX or MOVC instruction is used.
