grammed without chip erasing the device. In this case, data polling cannot be used for the value
0xFF, and the user will have to wait at least t

Operation
Read H (high or low) data o from Program memory at
word address a:b.
Write H (high or low) data i to Program Memory page
at word address b. Data low byte must be loaded
before Data high byte is applied within the same
address.
