TMPM330 - Keil

7.1.9 Port I (PI0~PI7)
Under development
TMPM330
The port I is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be
specified in units of bits. Besides the general-purpose port function, the port I performs the 16-bit timer
input/output function.
A reset allows all bits to perform as the general-purpose port and the port I to be put in input/ output
disable mode.
