(11) Cautions on Accessing Flash Memory Control Registers
1. Flash memory control register access state in each operating mode

2. When a flash memory control register is accessed in mode 2 (expanded mode with on-chip
3. To check for 12 V application/non-application in mode 3 (single-chip mode)
PP
The H8/3334YF has flash memory control registers located at addresses H'FF80 (FLMCR),
H'FF82 (EBR1), and H'FF83 (EBR2). These registers can only be accessed when 12 V is
applied to the flash memory program power supply pin, FV
Table 19.17 shows the area accessed for the above addresses in each mode, when 12 V is and
is not applied to FV
ROM enabled)
When a flash memory control register is accessed in mode 2, it can be read or written to if
12 V is being applied to FV
essential to confirm that 12 V is being applied to the FV
When address H'FF80 is accessed in mode 3, if 12 V is being applied to FV
read/written to, and its initial value after reset is H'80. When 12 V is not being applied to FV
FLMCR is a reserved area that cannot be modified and always reads H'FF. Since bit 7
