Brown-Out Detector Control Register (BODCR)
Partial of the BODCR control registers values are initiated by the flash configuration and partial
bits are write-protected bit. Programming write-protected bits needs to write “59h”, “16h”, “88h” to
address 0x5000_0100 to disable register protection. Reference the register REGWRPROT at
address GCR_BA+0x100

Low Voltage Reset Enable (write-protection bit)
The LVR function reset the chip when the input power voltage is lower than LVR circuit
setting. LVR function is enabled in default.
1 = Enabled Low Voltage Reset function – After enabling the bit, the LVR function will
be active with 100uS delay for LVR output stable. (default).
0 = Disabled Low Voltage Reset function
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 output status
1 = Brown Out Detector output status is 1. It means the detected voltage is lower than
BOD_VL setting. If the BOD_EN is 0, BOD function disabled , this bit always responds
0
0 = Brown Out Detector output status is 0. It means the detected voltage is higher than
BOD_VL setting or BOD_EN is 0
Brown Out Detector Low power Mode (write-protection 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.
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
