6.8 Pin function select register 1 (PINSEL1 - 0xE002C004)
Table 6:
The PINSEL1 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.
Function control for the pins P0.17 - P0.31 is effective only when the DBGSEL input is
pulled LOW during RESET.
