11.11 Stop Mode
When the MCU is put into stop mode, if the FLASH is in read mode, it
will be put into low-power standby. Exit from stop is possible with an
external interrupt, such as IRQ, keyboard interrupt, or reset.
The STOP instruction should not be executed while performing a
program or erase operation on the FLASH. When the MCU is put into
stop mode, the charge pump for the FLASH is disabled so that either a
program or erase operation will not continue. If the memory is in either
program mode (PGM = 1, HVEN = 1) or erase mode (ERASE = 1,
HEVEN = 1), then it will remain in that mode during stop. In this case,
exit from stop must be done with a reset rather than an interrupt because
if exiting stop with an interrupt, the memory will not be in read mode and
the interrupt vector cannot be read from the memory.
