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.
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 / Receive data in—USART0/UART mode
I/O General-purpose digital I/O / Transmit data out—USART0/UART mode
I/O General-purpose digital I/O / Analog input to brownout, supply voltage supervisor
Analog supply voltage, negative terminal. Supplies SD16, SVS, brownout, oscillator, and LCD resistive
divider circuitry.
Digital supply voltage, negative terminal.
Analog supply voltage, positive terminal. Supplies SD16, SVS, brownout, oscillator, and LCD resistive
divider circuitry; must not power up prior to DV_CC.
NOTE 1: LCD function selected automatically when applicable LCD module control bits are set, not with PxSEL bits.
