EPGM — EPROM Programming Bit
This read/write bit applies the voltage from the IRQ/VPP pin to the
EPROM. To write the EPGM bit, the ELAT bit must be set already.
Reset clears EPGM.
1 = Programming voltage (IRQ/VPP pin) applied to EPROM
0 = Programming voltage (IRQ/VPP pin) not applied to EPROM
NOTE:
Writing logic 1s to both the ELAT and EPGM bits with a single instruction
sets ELAT and clears EPGM. ELAT must be set first by a separate
instruction.
Bits [7:3] — Reserved
Take the following steps to program a byte of EPROM/OTPROM:
1. Apply the programming voltage, VPP, to the IRQ/VPP pin.
2. Set the ELAT bit.
3. Write to any EPROM/OTPROM address.
4. Set the EPGM bit and wait for a time, tEPGM.
5. Clear the ELAT bit.
3.6.3 EPROM Erasing
The erased state of an EPROM bit is logic 0. Erase the EPROM by
exposing it to 15 Ws/cm2 of ultraviolet light with a wavelength of 2537
angstroms. Position the ultraviolet light source one inch from the
EPROM. Do not use a shortwave filter.
