TMPM330 - Keil

7.1.5 Port E (PE0~PE6)
Under development
TMPM330
The port E is a general-purpose, 7-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 E performs the serial
interface function and the remote control signal preprocessor input function.
A reset allows all bits to perform as the general-purpose port and the port E to be put in input/ output
disable mode.
