6.10.1 Features
6.10 General purpose parallel I/O
6.9 Pin function select register 2 (PINSEL2 - 0xE002C014)
Table 7:
The PINSEL2 register controls the functions of the pins as per the settings listed in
Table
function is selected for a pin. For other functions direction is controlled automatically.
Settings other than those shown in the table are reserved, and should not be used.
Table 8:
Device pins that are not connected to a specific peripheral function are controlled by
the GPIO registers. Pins may be dynamically configured as inputs or outputs.
Separate registers allow setting or clearing any number of outputs simultaneously.
The value of the output register may be read back, as well as the current state of the
port pins.
