17[6]

O

General purpose digital output only pin.

Important: This pin MUST NOT be externally pulled LOW when RESET pin is LOW or

the JTAG port will be disabled.

P1.0 to P1.31

I/O Port 1: Port 1 is a 32-bit bidirectional I/O port with individual direction controls for each

bit. The operation of port 1 pins depends upon the pin function selected via the pin

connect block. Pins 0 through 15 of port 1 are not available.

P1.16/

16[6]

O
