NAME
FUNCTION
11
1
CLK
Clock Output. Default is 2.457MHz output clock for C.
22
2
UPIO2
User-Programmable Input/Output 2. See the UPIO2_CTRL Register section for
functionality.
33
3
UPIO3
User-Programmable Input/Output 3. See the UPIO3_CTRL Register section for
functionality.
44
4
UPIO4
User-Programmable Input/Output 4. See the UPIO4_CTRL Register section for
functionality.
55
5
DOUT
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.
66
6
SCLK
Serial-Clock Input. Clocks data in and out of the serial interface.
77
7DIN
Serial-Data Input. Data is clocked in on SCLK’s rising edge.
88
8
CS
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.
99
9
INT
Programmable Active-High/Low Interrupt Output. ADC, UPIO wake-up, alarm, and
voltage-monitor events.
10
CLK32K
32kHz Clock Input/Output. Outputs 32kHz clock for C. 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.
11
RESET
Active-Low Open-Drain Reset Output. Remains low while DVDD is below the 1.8V
voltage threshold and stays low for a timeout period (tDSLP) after DVDD rises above
the 1.8V threshold.
RESET also pulses low when the watchdog timer times out and
holds low during POR until the 32kHz oscillator stabilizes.
12
32KOUT
32kHz Crystal Output. Connect external 32kHz watch crystal between 32KIN and
32KOUT.
13
32KIN
32kHz Crystal Input. Connect external 32kHz watch crystal between 32KIN and
32KOUT.
14
SNO1
Analog Switch 1 Normally Open Terminal. Analog input to mux.
15
SCM1
Analog Switch 1 Common Terminal. Analog input to mux.
16
SNC1
Analog Switch 1 Normally Closed Terminal. Analog input to mux (open on POR).
17
SNO2
Analog Switch 2 Normally Open Terminal. Analog input to mux.
18
SCM2
Analog Switch 2 Common Terminal. Analog input to mux (open on POR).
19
SNC2
Analog Switch 2 Normally Closed Terminal. Analog input to mux.
20
OUT1
Amplifier 1 Output. Analog input to mux.
21
IN1-
Amplifier 1 Inverting Input. Analog input to mux.
22
IN1+
Amplifier 1 Noninverting Input
23
SWA
DACA SPST Shunt Switch Input. Connects to OUTA through a SPST switch.
24
FBA
DACA Force-Sense Feedback Input. Analog input to mux.
