Section 17 ROM
(1) Flash Code Control and Status Register (FCCS)
FCCS is configured by bits which request the error occurrence during programming or erasing
flash memory and the download of on-chip program.
Bit 7—Reserved: This bit is always read as 1. The write value should always be 1.
Bits 6 and 5—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 4—Flash Memory Error (FLER): Indicates an error occurs during programming and erasing
flash memory.
When FLER is set to 1, flash memory enters the error protection state.
This bit is initialized at a power-on reset or in hardware standby mode.
When FLER is set to 1, high voltage is applied to the internal flash memory. To reduce the
damage to flash memory, the reset must be released after the reset period of 100 μs which is
longer than normal.
