BPSCTR – Battery Protection Short-current Timing Register
BPOCTR – Battery Protection Over-current Timing Register
• Bit 7 – Res: Reserved Bits
This bit is reserved and will always read as zero.
• Bit 6:0 – SCPT6:0: Short-current Protection Timing
These bits control the delay of the Short-circuit Protection. The Short-circuit Timing can be set
with a step size of 62.5 µs as shown in
Table 20-2.
Notes:
Note:
• Bit 7:6 – Res: Reserved Bits
These bits are reserved and will always read as zero.
• Bit 5:0 – OCPT5:0: Over-current Protection Timing
These bits control the delay of the Over-circuit Protection. The Over-current Timing can be set
with a step size of 0.5 ms as shown in

Due to synchronization of parameters between clock domains, a guard time of 3 ULP oscillator
cycles + 3 CPU clock cycles is required between each time the BPSCTR register is written. Any
writing to the BPSCTR register during this period will be ignored.
