Description
Reset. Input pin, active low. An external 1 kΩ pull-up resistor is recommended with this pin.
JTAG Test Mode Select. Input pin. Used for debug and download.
General-Purpose Input and Output P1/External Interrupt Request 1/Serial Input Pin 0/Timer 0
input. This pin is a multifunction input/output pin offering four functions.
General-Purpose Input and General-Purpose Output P1.1/Serial Output. This is a dual function
input/output pin.
General-Purpose Input and General-Purpose Output P1.2/PWM External Sync Input. This is a dual
function input/output pin.
General-Purpose Input and General-Purpose Output P1.3/PWM External Trip Input. This is a dual
function input/output pin.
General-Purpose Input and General-Purpose Output P0.5.
General-Purpose Input and General-Purpose Output P0.6.
Digital Supply Pin.
Digital Ground.
DAC Output. Analog output pin.
Single-Ended or Differential Analog Input 5/External Reference Negative Input. This is a dual
function analog input pin. The ADC5 serves as the analog input for the auxiliary ADC. The
EXT_REF2IN− serves as the external reference negative input by ADC for the auxiliary channel.
Multifunction Analog Input Pin. This pin can be used for the single-ended or differential Analog
Input 4, which is the analog input for the auxiliary ADC, or it can be used for the external
reference positive input for the auxiliary channel.
Single-Ended or Differential Analog Input 3. Analog input for the auxiliary ADC.
Single-Ended or Differential Analog Input 2. Analog input for the auxiliary ADC.
Programmable Current Source. Analog output pin.
