REGWRPROT at address GCR_BA+0x100.
Brown Out Detector Interrupt Flag
1 = When Brown Out Detector detects the VDD is dropped down through the voltage of
BOD_VL setting or the VDD is raised up through the voltage of BOD_VL setting, this
bit is set to 1 and the brown out interrupt is requested if brown out interrupt is enabled.
0 = Brown Out Detector does not detect any voltage draft at VDD down through or up
through the voltage of BOD_VL setting.
Software can write 1 to clear this bit to zero.
Brown Out Reset Enable (write-protection bit)
1 = Enable the Brown Out “RESET” function
While the Brown Out Detector function is enabled (BOD_EN high) and BOD reset
function is enabled (BOD_RSTEN high), BOD will assert a signal to reset chip when
the detected voltage is lower than the threshold (BOD_OUT high).
0 = Enable the Brown Out “INTERRUPT” function
While the BOD function is enabled (BOD_EN high) and BOD interrupt function is
enabled (BOD_RSTEN low), BOD will assert an interrupt if BOD_OUT is high. BOD
interrupt will keep till to the BOD_EN set to 0. BOD interrupt can be blocked by
disabling the NVIC BOD interrupt or disabling BOD function (set BOD_EN low).
The default value is set by flash controller user configuration register config0 bit[20].
This bit is the protected bit. It means programming this needs to write “59h”, “16h”,
“88h” to address 0x5000_0100 to disable register protection. Reference the register
REGWRPROT at address GCR_BA+0x100.
Brown Out Detector Threshold Voltage Selection (write-protection bits)
The default value is set by flash controller user configuration register config0 bit[22:21]
This bit is the protected bit. It means programming this needs to write “59h”, “16h”,
“88h” to address 0x5000_0100 to disable register protection. Reference the register
REGWRPROT at address GCR_BA+0x100.
Brown Out Detector Enable (write-protection 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
This bit is the protected bit. It means programming this needs to write “59h”, “16h”,
“88h” to address 0x5000_0100 to disable register protection. Reference the register
REGWRPROT at address GCR_BA+0x100.
