The Mode Bit and the Security Bit
The TMP90P802A has the Security Bit in PROM cell.
If the Sercuity Bit is programmed to “0”, the content of
the PROM is disable to read in PROM mode.
How to Program the Security Bit.
1) Connect A15 pins to V
them to GND to program PROM]
2) Set programming address to 0000H.
3) To program the Security Bit, set D0 to “0”.
4) Set D2 ~ D7 to “1” respectively.
