The EPROM control register controls EPROM programming.
ELAT — EPROM Latch Control Bit
EPGM — EPROM Program Control Bit
Reset:
Read:
Write:
This read/write bit latches the address and data buses for
programming the EPROM. Clearing ELAT also clears the EPGM bit.
EPROM data cannot be read when ELAT is set.
This read/write bit applies the programming voltage from the
IRQ1/V
must be set already. The STOP instruction clears the EPGM bit.
Reset also clears EPGM.
