(9) Do not set or clear the VppE bit during execution of a program in flash memory.
Flash memory data cannot be read normally when the VppE bit is set or cleared. After the VppE
bit is cleared, flash memory data can be rewritten after waiting for the elapse of the Vpp enable
setup time (t
verification (verification during programming, erasing, or prewriting). After the VppE is cleared,
wait for the elapse of the flash memory read setup time before performing program execution and
data reading in flash memory.
(10) Do not use interrupts while programming or erasing flash memory.
When Vpp is applied, disable all interrupt requests, including NMI, to give the programming or
erase operation (including RAM emulation) the highest priority.
(11) The Vpp flag is set and cleared by a threshold decision on the voltage applied to the
Vpp pin. The threshold level is approximately in the range from Vcc +2 V to 11.4 V.
When this flag is set, it becomes possible to write to the flash memory control register (FLMCR)
and the erase block registers (EBR1 and EBR2), even though the Vpp voltage may not yet have
