IMPORTANT: Microcontroller with EPROM. The window on the chip must be covered before performing any operation on the chip. The following describes the buffer setup: Addresses $0020 thru $0027 are PEPROM.Addresses $0700 to $1EFF are user EPROM.The Mask Option Registers(MOR) is located at $1FF0 and $1FF1.Bit 7 of the MOR at address $1FF0 contains the security bit(EPMSEC)to program this bit please use Device/Secure command. There is only one bit(OPT bit 6) available for reading and verifying at addres $1FF0.the device will fail Compare when data other than 40h or 00h is set at this location in the data buffer.Bit 0 of the MOR at address $1FF0 is COPC bit. It is a write-only bit. It can be programmed to 1 or 0but will always read back 0.Please refer to the user’s manual for information about this option.Addresses $1FF2 to $1FFF are user vectors.
