Clock Output. Default is 2.457MHz output clock for the μC.
User-Programmable Input/Output 2. See the UPIO2_CTRL Register section for functionality.
User-Programmable Input/Output 3. See the UPIO3_CTRL Register section for functionality.
User-Programmable Input/Output 4. See the UPIO4_CTRL Register section for functionality.
Serial-Data Output. Data is clocked out on SCLK’s falling edge. High impedance when
UPIO/SPI pass-through mode is enabled, DOUT mirrors the state of UPIO1.
Serial-Clock Input. Clocks data in and out of the serial interface.
Serial-Data Input. Data is clocked in on SCLK’s rising edge.
Active-Low Chip-Select Input. Data is not clocked into DIN unless
impedance. High impedance when
mirrors the state of UPIO1.
Programmable Active-High/Low Interrupt Output. ADC, UPIO wake-up, alarm, and voltage-monitor events.
32kHz Clock Input/Output. Outputs 32kHz clock for the μC. Can be programmed as an input by enabling
the IO32E bit to accept an external 32kHz input clock. The RTC, PWM, and watchdog timer always use the
internal 32kHz clock derived from the 32kHz crystal.
Active-Low, Open-Drain Reset Output. Remains low while DV
stays low for a timeout period (t
when the watchdog timer times out and holds low during POR until the 32kHz oscillator stabilizes.
32kHz Crystal Output. Connect an external 32kHz watch crystal between 32KIN and 32KOUT.
32kHz Crystal Input. Connect an external 32kHz watch crystal between 32KIN and 32KOUT.
