On-Chip Debug Interface, serial data.
On-Chip Debug Interface, serial clock.
Crystal1: input to the inverting oscillator
amplifier and input to the internal clock
generator circuits.
Crystal 2: output from the inverting
oscillator amplifier.
A high on this pin for 24 clock cycles while
the oscillator is running, resets the device.
Output of the internal LDO (Low Drop-Out
voltage regulator): s
ground through an external capacitor
(4.7μF~100μF) in the application with
VDD power higher than 3.6V; and tied to
VDD pin in the application with VDD
power lower than 3.6V.
Power supply, for normal, idle and power-
down operation.
Ground, 0 V reference.
