13.2 Introduction
This section describes how to program the 6160-byte erasable
programmable read-only memory/one-time programmable read-only
memory (EPROM/OTPROM), the mask option register (MOR), and the
EPROM security bit (EPMSEC).
NOTE: In packages with no quartz window, the EPROM functions as one-time
programmable ROM (OTPROM).
