ATmega406
When the PWMOC is cleared (zero), the CFE bit and the battery protection circuitry controls the
OC output. When this bit is set (one), the OC output will be the logical AND of the PWM output
from the 8-bit Timer/Counter0 and the inverse of CURRENT_PROTECTION from the Battery
Protection circuitry.
• Bit 4 – PWMOPC: Pulse Width Modulation of OPC output
When the PWMOPC is cleared (zero), the PFD bit and the battery protection circuitry controls
the OPC output. When this bit is set (one), the OPC output will be the logical AND of the PWM
output from the 8-bit Timer/Counter0 and the inverse of CURRENT_PROTECTION from the
Battery Protection circuitry.
• Bit 3 – CPS: Current Protection Status
The CPS bit shows the status of the Current Protection. This bit is set (one) when the Current
Protection Timer is activated, and is cleared (zero) when the hold-off time has elapsed.
• Bit 2 – DFE: Discharge FET Enable
When the DFE bit is cleared (zero), the Discharge FET will be disabled regardless of the state of
the Battery Protection circuitry. When this bit is set (one), the Discharge FET state is determined
by the Battery Protection circuitry. This bit will be cleared when CURRENT_PROTECTION is set
(one).
• Bit 1 – CFE: Charge FET Enable
When the CFE bit is cleared (zero), the Charge FET will be disabled regardless of the state of
the Battery Protection circuitry. When this bit is set (one), the Charge FET state is determined by
the Battery Protection circuitry. This bit will be cleared when CURRENT_PROTECTION is set
(one).
• Bit 0 – PFD: Precharge FET Disable
The PFD bit provides complete control of the Precharge FET. When the PFD bit is cleared
(zero), the Precharge FET will be enabled. When the PFD bit is cleared, the Precharge FET will
be enabled. When the PFD bit is set (one), the Precharge FET will be disabled. This bit will be
cleared when the CURRENT_PROTECTION is set (one)
