Clock Output. Default is 2.457MHz output clock for 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 CS is high. When
UPIO/SPI passthrough 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 CS is low. When CS is high, DOUT is
high impedance. High impedance when CS is high. When UPIO/SPI passthrough mode is enabled, DOUT
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 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 Input. Connect external 32kHz watch crystal between 32KIN and 32KOUT or drive with
CMOS level as shown in Figure 25.
