Notes: 1. Follow the program/erase algorithms shown in section 6 when making the settings.
2. Indicates the programming time per byte (the time during which the P bit is set in the
flash memory control register (FLMCR)). Does not include the program-verify time.
3. Indicates the time to erase all blocks (32 kB) (the time during which the E bit is set in
FLMCR). Does not include the prewrite time before erasing of the erase-verify time.
4. After powering on when using an external clock, when the programming voltage (V
PP
) is
switched from 12 V to V
CC
, an interval at least equal to the read setup time must be
allowed to elapse before reading the flash memory.
When
V
PP
is released, this specifies the setup time from the point at which the V
PP
voltage reaches the V
CC
+ 2 V level until the flash memory is read.
