Description
analog ground supply
regulated supply voltage (3.3 V ± 10 %) from the internal
regulator; used to connect a 0.1 μF decoupling capacitor and
pull-up resistor on pin DP
Remark: Cannot be used to supply external devices.
V
DMA request output (4 mA; programmable polarity, see
Table
to start a DMA transfer
3.3 V tolerant I/O pad
DMA acknowledge input (programmable polarity, see
used by the DMA controller to signal the start of a DMA transfer
requested by the ISP1183; when not in use, connect this pin to
ground through a 10 kΩ resistor
When the RESET_N pin is LOW, ensure that the DACK and
WAKEUP pins are LOW. Otherwise, the device will enter test
mode.
3.3 V tolerant I/O pad
reset input (Schmitt trigger); a LOW level produces an
asynchronous reset
When the RESET_N pin is LOW, ensure that the DACK and
WAKEUP pins are LOW. Otherwise, the device will enter test
mode.
3.3 V tolerant I/O pad
address input; selects command (A0 = HIGH) or data (A0 =
LOW)
3.3 V tolerant I/O pad
I/O power supply; add a decoupling capacitor of 0.1 μF (1.65 V to
3.6 V); see
