CHG
The CHG enable bit allows direct control of the charge current source and the discharge device and
also reflects the state of the discharge device. This bit is cleared by a reset of the device.
1 = If the ISEN bit is also set, the charge current source is sourcing current out of the PB0/AN0 pin.
Writing a logic 1 enables the charging current out of the PB0/AN0 pin.
0 = The discharge device is sinking current into the PB0/AN0 pin. Writing a logic 0 disables the
charging current and enables the discharging current into the PB0/AN0 pin, if the ISEN bit is
also set.
ATD1–ATD2
The ATD1–ATD2 enable bits select one of the four operating modes used for making A/D conversions
via the single-slope method.These four modes are given in Table 8-3. These bits have no effect if the
ISEN enable bit is cleared. These bits are cleared by a reset of the device and thereby return the
analog subsystem to the manual A/D conversion method.
