2.6 EPROM/OTPROM
An MCU with a quartz window has 504 bytes of erasable, programmable
ROM (EPROM). The quartz window allows EPROM erasure with
ultraviolet light. In an MCU without the quartz window, the EPROM
cannot be erased and serves as 504 bytes of one-time programmable
ROM (OTPROM). Addresses $0020–$03EF contain 496 bytes of user
EPROM/OTPROM. The eight addresses from $03F8 to $03FF are
EPROM/OTPROM locations reserved for interrupt vectors and reset
vectors.
2.7 Personality EPROM/OTPROM
An MCU with a quartz window has a 64-bit array of erasable,
programmable ROM (EPROM) to serve as a personality EPROM. The
quartz window allows EPROM erasure with ultraviolet light. In an MCU
without the quartz window, the personality EPROM cannot be erased
and serves as a 64-bit array of OTPROM.
