Brown Out Detector Low power Mode (write-protected bit)
1= Enable the BOD low power mode
0= BOD operate in normal mode (default)
The BOD consumes about 100uA in normal mode, the low power mode can reduce the
current to about 1/10 but slow the BOD response.
Brown Out Detector Interrupt Flag
1= When Brown Out Detector detects the V
setting or the V
and the brown out interrupt is requested if brown out interrupt is enabled.
0= Brown Out Detector does not detect any voltage draft at V
through the voltage of BOD_VL setting.
Brown Out Reset Enable (initiated & write-protected bit)
1= Enable the Brown Out “RESET” function, when the Brown Out Detector function is
enable and the detected voltage is lower than the threshold then assert a signal to reset
the chip
The default value is set by flash controller user configuration register config0 bit[20]
0= Enable the Brown Out “INTERRUPT” function, when the Brown Out Detector function
is enable and the detected voltage is lower than the threshold then assert a signal to
interrupt the MCU Cortex-M0
When the BOD_EN is enabled and the interrupt is assert, the interrupt will keep till to the
BOD_EN set to “0”. The interrupt for CPU can be blocked by disable the NVIC in CPU
for BOD interrupt or disable the interrupt source by disable the BOD_EN and then re-
enable the BOD_EN function if the BOD function is required
Brown Out Detector Threshold Voltage Selection (initiated & write-protected bit)
The default value is set by flash controller user configuration register config0 bit[22:21]
Brown Out Detector Enable (initiated & write-protected bit)
The default value is set by flash controller user configuration register config0 bit[23]
1= Brown Out Detector function is enabled
0= Brown Out Detector function is disabled
