TMPM330 - Keil

7.1.8 Port H (PH0~PH7)
Under development
TMPM330
The port H 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 H performs the functions of
the 16-bit timer input and the operation mode setting.
While a reset signal is in “0”state, the PH0 input is enabled. At the rising edge of the reset signal, if PI0
is “1”, it enters single mode and executes boot from the on-board flash memory. If PI0 is “0”, it enters
single boot mode and executes boot from the stored boot program. For details of single boot mode,
refer to “Chapter 17 Flash Memory Operation”.
Releasing a reset allows all bits to perform as the general-purpose port and the port H to be put in
input/ output disable mode.
