Notes on Use of Emulation in RAM:
1. Flash write enable (FWE) application and releasing
As in on-board program mode, care is required when applying and releasing FWE to prevent
erroneous programming or erasing. To prevent erroneous programming and erasing due to
program runaway during FWE application, in particular, the watchdog timer should be set
when the PSU, P, ESU, or E bit is set to 1 in FLMCR1, even while the emulation function is
being used. For details, see section 17.9, Flash Memory Programming and Erasing Precautions.
2. NMI input disabling conditions
When the emulation function is used, NMI input is disabled when the P bit or E bit is set to 1
in FLMCR, in the same way as with normal programming and erasing.
The P and E bits are cleared by a reset (including a watchdog timer reset), in standby mode,
when a high level is not being input to the FWE pin, or when the SWE bit in FLMCR is 0
while a high level is being input to the FWE pin.
