Legend:
RA = Address of the memory location to be read
PA = Address of the memory location to be programmed
Addresses are latched on the falling edge of the write pulse.
SA = Address of the sector
BA = Bank Address
RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the rising edge of write pulse.
SGA = Sector group address to be protected. Set sector group address and (A6, A5, A4, A3, A2, A1, A0)
= (0, 1, 1, 1, 0, 1, 0)
SD = Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
HRA = Address of the HiddenROM area (000000h to 00007Fh)
HRBA = Bank Address of the HiddenROM area (A21 = A20 = A19 = VIL)
RD(0) = DQ0 data, RD(1) = DQ1 data. PPB Lock bit is read on DQ1 and PPB or DPB are read on DQ0.
If set, DQ0/DQ1=1. If cleared, DQ0/DQ1=0.
OPBP = (A6, A5, A4, A3, A2, A1, A0) is (X, 0, 1, 1, 0, 1, 0)
SLA = Address of the sector to be locked. Set sector address (SA) and either A6 = 1 for unlocked or
A6 = 0 for locked
PWA/PWD = Password Address/Password Data
PL = (A6, A5, A4, A3, A2, A1, A0) is (X, 0, 0, 1, 0, 1, 0)
SPML = (A6, A5, A4, A3, A2, A1, A0) is (X, 0, 1, 0, 0, 1, 0)
WP = (A6, A5, A4, A3, A2, A1, A0) is (X, 1, 1, 1, 0, 1, 0)
