Register Description
CHGDCSR – Charger Detect Control and Status Register
•
• Bit 7:5 – Reserved
These bits are reserved and will always read as zero.
• Bit 4 – BATTPVL: BATT pin Voltage Level
BATTPVL will read one as long when the Charger Detect module is enabled and the BATT pin
voltage is above the VPOT level. Otherwise the BATTPVL will read zero.
• Bit 3:2 – CHGDISC[1:0]: Charger Detect Interrupt Sense Control
Edges in the CHARGER_PRESENT signal shown in
vate a Charger Detect Interrupt if the SREG I-flag and the interrupt enable bit in CHGDCSR are
set. By writing the CHGDISC bits to the values shown in
generating interrupt is configured. When changing the CHGDISC bits, an interrupt can occur.
Therefore, it is recommended to first disable the Interrupt by clearing its CHGDIE bit in the
CHGDICSR Register. Finally, the Charger Detect interrupt flag should be cleared by writing a
logical one to CHGDIF bit before the interrupt is re-enabled.
Table 22-1.
• Bit 1 – CHGDIF: Charger Detect Interrupt Flag
Depending on the configuration of the CHGDISC bits in the CHGDCSR, this bit is set when a
charger is either connected or disconnected. The Charger Detect Interrupt is executed if the
CHGDIE bit and the I-bit in SREG are set. This bit is cleared by hardware when executing the
corresponding interrupt handling vector or alternatively by writing a logical one to the CHGDIF. It
is recommended to write this bit to one when setting CHGDIE.
• Bit 0 – CHGDIE: Charger Detect Interrupt Enable
When the CHGDIE bit is set (one), and the I-bit in the Status Register is set (one), the Charger
Detect Interrupt is enabled.

When disabling the Charge-FET the Charger Detect module is automatically enabled and a
charger appear to be connected.
