Extend Ale:
If this bit is set, the time of the ALE pulse is T
OSC
. Clearing this bit
extends the time of the ALE pulse from T
OSC
to 3T
OSC
, which adds
one external wait state.

Page Mode Select:
Clear this bit for page-mode (A15:8/D7:0 on P2, and A7:0 on P0). Set
this bit for nonpage-mode (A15:8 on P2, and A7:0/D7:0 on P0
(compatible with MCS 51 microcontrollers)).
NOTE:
Factory-programmed ROM and OTPROM versions of 8XC151SA/SB use configuration byte information supplied in a
separate hexadecimal disk file. 8XC151SA/SB devices without internal ROM/OTPROM arrays fetch configuration byte
information from external application memory based on an internal address range of FFF9:8H.
