4 / 20 page 4 8042AS–AVR–09/08 ATmega16HVB/32HVB 1.2.13 PPI/NNI Unfiltered positive/negative input from external current sense resistor, used by the battery pro- tection circuit, for over-current and short-circuit detection. For details, see ”Battery Protection” on page 135. 1.2.14 NV/PV1/PV2/PV3/PV4 NV, PV1, PV2, PV3, and PV4 are the inputs for battery cells 1, 2, 3 and 4, used by the Voltage ADC to measure each cell voltage. For details, see ”Voltage ADC – 7-channel General Purpose 12-bit Sigma-Delta ADC” on page 118. 1.2.15 PVT Defines the source voltage level for the Charge FET driver. For details, see ”FET Driver” on page 147. 1.2.16 BATT Input for detecting when a charger is connected. Defines the source voltage level for the Dis- charge FET driver. For details, see ”FET Driver” on page 147. 1.2.17 RESET/dw Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running. The minimum pulse length is given in Table 11 on page 38. Shorter pulses are not guaranteed to generate a reset. This pin is also used as debugWIRE communication pin. |
