FLMCR1—Flash Memory Control Register 1
Note: * Determined by the state of the FWE pin.
Bit
Initial value
Read/Write
Notes: 1. This register is not present in the mask ROM version, and an attempt to read it will return an undefined value.
Flash write enable bit
0 When a low level is input to the FWE pin (hardware-protected state)
1
When a high level is input to the FWE pin
2. To access this register, set the FLSHE bit to 1 in serial control register X (SCRX). Even if FLSHE = 1, if the chip
:
:
:
is in a mode in which the on-chip flash memory is disabled, a read will return H'00 and writes are invalid. Writes
to this register are also invalid when the FWE bit in FLMCR1 is not set to 1.
