19.6.4
The flash memory is controlled by means of the pins shown in table 19-10.
Table 19-10 Flash Memory Pins
19.6.5
The registers used to control the on-chip flash memory when enabled are shown in table 19-11.
In order for these registers to be accessed, the FLSHE bit must be set to 1 in SYSCR2 (except RAMER).
Table 19-11 Flash Memory Registers
Notes: 1. Lower 16 bits of the address.
2. Flash memory registers are selected by the FLSHE bit in system control register 2 (SYSCR2).
3. In modes in which the on-chip flash memory is disabled, a read will return H'00, and writes are invalid. Writes
4. When a high level is input to the FWE pin, the initial value is H'80.
5. When a low level is input to the FWE pin, or if a high level is input and the SWE bit in FLMCR1 is not set, these
6. FLMCR1, FLMCR2, EBR1, and EBR2 are 8-bit registers. Only byte accesses are valid for these registers, the
