I/O
DESCRIPTION
I/O General-purpose digital I/O / Comparator_A input
I/O General-purpose digital I/O / Timer_A, clock signal TACLK input / ACLK output (divided by 1, 2, 4, or 8)
I/O General-purpose digital I/O / input clock TBCLK—Timer_B7 / submain system clock SMCLK output
I/O
General-purpose digital I/O / switch all PWM digital output ports to high impedance—Timer_B7 TB0 to TB6
/ SVS: output of SVS comparator
I/O General-purpose digital I/O / Timer_A, Capture: CCI1A input, compare: Out1 output
I/O
General-purpose digital I/O / Timer_A. Capture: CCI0B input / MCLK output.
Note: TA0 is only an input on this pin / BSL receive
I/O General-purpose digital I/O / Timer_A. Capture: CCI0A input, compare: Out0 output / BSL transmit
O Output terminal of crystal oscillator XT2
I Input port for crystal oscillator XT2. Only standard crystals can be connected.
I/O Test data output port. TDO/TDI data output or programming data input terminal
I Test data input or test clock input. The device protection fuse is connected to TDI/TCLK.
I Test mode select. TMS is used as an input port for device programming and test.
I Test clock. TCK is the clock input port for device programming and test.
I Reset input or nonmaskable interrupt input port
I/O General-purpose digital I/O, analog input a0—12-bit ADC
I/O General-purpose digital I/O, analog input a1—12-bit ADC
I/O General-purpose digital I/O, analog input a2—12-bit ADC
Analog supply voltage, negative terminal. Supplies SVS, brownout, oscillator, comparator_A, ADC12,
port 1, and LCD resistive divider circuitry.
Digital supply voltage, negative terminal.
Analog supply voltage, positive terminal. Supplies SVS, brownout, oscillator, comparator_A, ADC12, port 1,
and LCD resistive divider circuitry; must not power up prior to DV_CC1/DV_CC2.
