Notes:
1. At power-up, Vcc must rise from 2.0 V to Vcc min in less than 25 ms, otherwise delay conguration by pulling PROGRAM
Low until Vcc is valid.
2. The rst Data byte is loaded and CCLK starts at the end of the rst RCLK active cycle (rising edge).
This timing diagram shows that the EPROM requirements are extremely relaxed. EPROM access time can be longer than
500 ns. EPROM data output has no hold-time requirements.
