Preliminary data
6.6 Pin connect block
6.7 Pin function select register 0 (PINSEL0 - 0xE002C000)
Table 4:
The pin connect block allows selected pins of the microcontroller to have more than
one function. Configuration registers control the multiplexers to allow connection
between the pin and the on chip peripherals. Peripherals should be connected to the
appropriate pins prior to being activated, and prior to any related interrupt(s) being
enabled. Activity of any enabled peripheral function that is not mapped to a related
pin should be considered undefined.
The Pin Control Module contains three registers as shown in
