NOTES:
1. The PROG

pulse waveform is shown in Figure 19.
2. 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.
3. When programming the lock bits, the data bits on port 2 are don’t care. Identify the lock bits with the address as follows:
LB3 - 0003H, LB2 - 0002H, LB1 - 0001H.
4. The three lock bits are verified in a single operation. The states of the lock bits appear simultaneously at port 2 as
follows: LB3 - P2.3, LB2 - P2.2. LB1 - P2.1. High
