2.6.2 EPROM Programming Register
MC68HC705J1A — Rev. 4.0
Address:
The EPROM programming register (EPROG) contains the control bits
for programming the EPROM/OTPROM.
ELAT — EPROM Bus Latch Bit
MPGM — MOR Programming Bit
EPGM — EPROM Programming Bit
Reset:
Read:
Write:
This read/write bit latches the address and data buses for
EPROM/OTPROM programming. Clearing the ELAT bit automatically
clears the EPGM bit. EPROM/OTPROM data cannot be read while
the ELAT bit is set. Reset clears the ELAT bit.
This read/write bit applies programming power from the IRQ/V
to the mask option register. Reset clears MPGM.
This read/write bit applies the voltage from the IRQ/V
EPROM. To write the EPGM bit, the ELAT bit must be set already.
Reset clears EPGM.
