EPROM/OTPROM
4.4 EPROM/OTPROM Control Register
Technical Data
56
Address:
The EPROM control register controls EPROM/OTPROM programming.
ELAT — EPROM/OTPROM Latch Control Bit
EPGM — EPROM/OTPROM Program Control Bit
$FE07
Reset:
Read:
Write:
This read/write bit latches the address and data buses for
programming the EPROM/OTPROM. Clearing ELAT also clears the
EPGM bit. EPROM/OTPROM data cannot be read when ELAT is set.
This read/write bit applies the programming voltage from the
IRQ1/V
ELAT bit must be set already. Reset clears the EPGM bit.
