Take the following steps to program a byte of EPROM:
1.
Apply 16.5 V to the IRQ/V
PP
pin.
2.
Set the LATCH bit.
3.
Write to any EPROM address.
4.
Set the EPGM bit for a time t
EPGM
to apply the programming voltage.
5.
Clear the LATCH bit.
6.1.3.2 EPROM Erasing
The erased state of an EPROM bit is zero. Erase the EPROM by exposing it to 15

of ultraviolet light with a wavelength of 2537 angstroms. Position the
ultraviolet light source 1 inch from the EPROM. Do not use a shortwave filter.
NOTE
Windowed packages must have the window covered during
programming and operation.
6.1.4 Bootloader ROM
Addresses $0F01–$0FEF contain the bootloader ROM, which can copy and verify
the contents of an external EPROM to the on-chip EPROM. See
