(4) Runaway prevention using SFR protection register
from runaway caused by stopping of the clock or by changes to the memory control
register (Memory controller, MMU) which prevent fetch operations..
by setting up a double key to EMCCR1 and EMCCR2 registers.
executed with protection in the ON state.
(Purpose)
Prevention of program runaway caused by introduction of noise.
Write operations to a specified SFR are prohibited so that the program is protected
Runaway error handling is also facilitated by INTP0 interruption.
Specified SFR list
(Operation explanation)
Execute and release of protection (write operation to specified SFR) becomes possible
Protection state can be confirmed by reading EMCCR0<PROTECT>.
At reset, protection becomes OFF.
INTP0 interruption also occurs when a write operation to the specified SFR is
