Table 43.
1. The variable P is a pointer which is defined at CFI offset 015h.
2. Bank regions. There are two bank regions, see Tables
3. Although the device supports Page Read mode, this is not described in the datasheet as its use is not
(P+30)h = 13Ah 02h
(P+31)h = 13Bh 03h
advantageous in a multiplexed device.
