System Control Unit - SCU
SMR
System Mode Register
1.5.1
The previous operating mode is shown in this register. The previous operating mode will be saved in this register after
reset event. There are two controllable bits in power down mode. One is LSI On/Off control and the other is VDC On/Off
control in power down mode.
System Mode Register is 16-bit register.

SRCR
System Reset Control Register
1.5.2
It is possible to check if chip is in power down mode. To use STBO output function, it should be set as STBO that has
output mode in Pin Mux. And It is possible to reset MCU as SWRST bit set.
System reset control register is 8-bit register.
