19.7.2
FLMCR2 is an 8-bit register that monitors the presence or absence of flash memory program/erase protection (error
protection) and performs setup for flash memory program/erase mode. FLMCR2 is initialized to H'00 by a reset, and in
hardware standby mode. The ESU and PSU bits are cleared to 0 in software standby mode, hardware protect mode, and
software protect mode.
When on-chip flash memory is disabled, a read will return H'00.
Bit 7—Flash Memory Error (FLER): Indicates that an error has occurred during an operation on flash memory
(programming or erasing). When FLER is set to 1, flash memory goes to the error-protection state.
Bits 6 to 2—Reserved: These bits cannot be modified and are always read as 0.
Bit 1—Erase Setup (ESU): Prepares for a transition to erase mode. Set this bit to 1 before setting the E bit to 1 in
FLMCR1. Do not set the SWE, PSU, EV, PV, E, or P bit at the same time.
Bit 0—Program Setup (PSU): Prepares for a transition to program mode. Set this bit to 1 before setting the P bit to 1 in
FLMCR1. Do not set the SWE, ESU, EV, PV, E, or P bit at the same time.
