BPSCTR – Battery Protection Short-circuit Timing Register
• Bit 4 – SCD: Short Circuit Protection Disabled
When the SCD bit is set, the Short-circuit Protection is disabled. The Short-circuit Detection will
be disabled, and any Short-circuit condition will be ignored.
• Bit 3 – DOCD: Discharge Over-current Protection Disabled
When the DOCD bit is set, the Discharge Over-current Protection is disabled. The Discharge
Over-current Detection will be disabled, and any Discharge Over-current condition will be
ignored.
• Bit 2 – COCD: Charge Over-current Protection Disable
When the COCD bit is set, the Charge Over-current Protection is disabled. The Charge Over-
current Detection will be disabled, and any Charge Over-current condition will be ignored.
• Bit 1 – DHCD: Discharge High-current Protection Disabled
When the DHCD bit is set, the Discharge High-current Protection is disabled. The Discharge
High-current Detection will be disabled, and any Discharge High-current condition will be
ignored.
• Bit 0 – CHCD: Charge High-current Protection Disable
When the CHCD bit is set, the Charge High-current Protection is disabled. The Charge High-cur-
rent Detection will be disabled, and any Charge High-current condition will be ignored.
Note:
• Bit 7 – Res: Reserved Bits
This bit is reserved and will always read as zero.
• Bit 6:0 – SCPT6:0: Short-circuit 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 23-2.
Bit
(0xFA)
Read/Write
Initial Value
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 BPCR register is written. Any writ-
ing to the BPCR register during this period will be ignored.

cuit Delay Time.
