Description
Digital Supply Voltage. Must be tied to +2.7 to +3.6 V.
Digital Ground. Must be tied to Ground.
Analog Supply Voltage. Must be tied to +2.7 to +3.6 V.
Analog Ground. Must be tied to Ground.
JTAG Test Mode Select with internal pull-up.
JTAG Test Clock with internal pull-up.
JTAG Test Data Input with internal pull-up. TDI is latched on the
rising edge of TCK.
TDO on the falling edge of TCK. TDO output is a tri-state driver.
low when VDD is <2.7 V and MONEN is high. An external source
can initiate a system reset by driving this pin low.
Crystal Input. This pin is the return for the internal oscillator circuit
for a crystal or ceramic resonator. For a precision internal clock,
connect a crystal or ceramic resonator from XTAL1 to XTAL2. If
overdriven by an external CMOS clock, this becomes the system
clock.
ceramic resonator.
VDD Monitor Enable. When tied high, this pin enables the internal
VDD monitor, which forces a system reset when VDD is < 2.7 V.
When tied low, the internal VDD monitor is disabled.
DAC Voltage Reference Input (F021/3 only).
ADC0 and ADC1 Voltage Reference Input.
ADC0 Voltage Reference Input.
ADC1 Voltage Reference Input.
