PGM and RST must both be low during a read cycle. I/O should not be driven (except by the external pullup resistor).

Notes:
1. During any Erase or Write operation, PGM must fall before the falling edge of CLK at the end of tCHP (recommend a mini-
mum setup of 1 µsec).
2. After the rising edge of PGM to initiate the Erase/Write operation, delay at least tDV (2 µsec) before driving data on the I/O
contact.
