Flash Program Time
Software Reset
Writing 1 to this bit to start software reset.
It is cleared by hardware after reset is finished.
ISP Fail Flag
This bit is set by hardware when a triggered ISP meets any of the following conditions:
(1) APROM writes to itself.
(2) LDROM writes to itself.
(3) Destination address is illegal, such as over an available range.
Note: Write 1 to clear this bit to zero.
LDROM Update Enable
LDROM update enable bit.
1 = LDROM can be updated when the MCU runs in APROM.
0 = LDROM cannot be updated
Config Update Enable
Writing this bit to 1 enables s/w to update Config value by ISP procedure regardless of
program code is running in APROM or LDROM.
1 = Config update enable
0 = Config update disable
Reserved
Boot Select
This bit is protected bit. Set/clear this bit to select next booting from LDROM/APROM,
respectively. This bit also functions as MCU booting status flag, which can be used to
check where MCU booted from. This bit is initiated with the inversed value of CBS
