Section 17 ROM
(1) When an interrupt, such as NMI, has occurred during programming/erasing
(2) When the relevant block area of flash memory is read during programming/erasing (including
(3) When a SLEEP instruction (including software standby mode) is executed during
(4) When a bus master other than the CPU, such as DTC or BREQ, has obtained the bus right
Error protection is cancelled only by a power-on reset or by hardware-standby mode. Note that the
reset should only be released after providing a reset input over a period longer than the normal 100
μs period. Since high voltages are applied during programming/erasing of the flash memory, some
voltage may remain after the error-protection state has been entered. For this reason, it is
necessary to reduce the risk of damage to the flash memory by extending the reset period so that
the charge is released.
The state-transition diagram in figure 17.75 shows transitions to and from the error-protection
state.
