Multiple-Use Pins. Configurable as DIO or its alternate
function. Alternate functions with proper selection of
associated I/O RAM registers are:
DIO0 = WPULSE (31)
DIO1 = VPULSE (30)
DIO2 = SDCK (29)
DIO3 = SDATA (28)
DIO6 = XPULSE (25)
DIO7 = YPULSE (24)
DIO8 = DI (23)
Unused pins must be configured as outputs or
terminated to V3P3/GNDD.
SPI interface pins.
Emulator port pins. These pins are activated when the
ICE_E pin is pulled high.
ICE enable. For production units, this pin should be
pulled to GND to disable the emulator port.
Multiplexer/clock output pins.
Chip reset: This input pin is used to reset the chip into a
known state. For normal operation, this pin is pulled low.
To reset the chip, this pin is pulled high. This pin has an
internal 30 μA (nominal) current source pull-down. No
external reset circuitry is necessary.
UART0 input. If this pin is unused it must be
terminated to V3P3D or GNDD.
UART0 output.
Enables Production Test.
This pin must be grounded in normal operation.
Push button input. This pin must be at GNDD when not
active or unused. PB does not have an internal pull-up or
pull-down resistor.
Do not connect this pin.
