Programming/Erasing Interface Registers
The programming/erasing interface registers are as described below. They are all 8-bit registers
that can be accessed in bytes.
(1) Flash Code Control and Status Register (FCCS)
FCCS is configured by bits which request the monitor of the FWE pin state and error
occurrence during programming or erasing flash memory and the download of the on-chip
program.
