The MCU Reset is similar with CHIP Reset. The difference is that BS(FMC_ISPCTL[1]) will not be
reloaded from CONFIG0 setting and keep its original software setting for booting from APROM or
LDROM. User can set the SYSRESETREQ(AIRCR[2]) to 1 to assert the MCU Reset.

CPU is in sleep state and all
clocks stop except LXT and
LIRC. SRAM content retended.
Chip is in normal mode after CPU executes WFI instruction. CPU sets sleep mode enable
system reset released
and power down enable and
executes WFI instruction.
