19.15.8 Pin Configuration
The flash memory is controlled by means of the pins shown in table 19-31.
Table 19-31 Flash Memory Pins
19.15.9 Register Configuration
The registers used to control the on-chip flash memory when enabled are shown in table 19-32.
In order to access the FLMCR1, FLMCR2, EBR1, and EBR2 registers, the FLSHE bit must be set to 1 in SYSCR2
(except RAMER).

2. Flash memory. Registers selection is performed 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.
4. If a high level is input and the SWE bit in FLMCR1 is not set, these registers are initialized to H'00.
5. FLMCR1, FLMCR2, EBR1, and EBR2 are 8-bit registers. Only byte accesses are valid for these registers, the
6. The SYSCR2 register can only be used in the F-ZTAT version. In the masked ROM version this register will
access requiring 2 states.
return an undefined value if read, and cannot be modified.
