Notes 1 :
When the expansion function select bit (bit 5 of particular function select register 1; Figure 62) is “1”,
bits 2, 5, 6 and 7 can be written and changed.
2 :
When accessing the internal memory area, CS
i
is not output. When only accessing the external area, CS
i
output is valid.
3 :
Select function of bits 6 and 7 is valid when both the CS
1
, CS
2
function select bit and the CS
3
function select bit (chip
select control register) are “1”.
