6.8 Pin function select register 1 (PINSEL1 - 0xE002 C004)
The PINSEL1 register controls the functions of the pins as per the settings listed in
Table 7. The direction control bit in the IODIR register is effective only when the GPIO
function is selected for a pin. For other functions direction is controlled automatically.
Remark: The primary JTAG port and the trace port can be selected only through the
DBGSEL pin at reset (Debug mode). Function control for the pins P0[31:17] is effective
only when the DBGSEL input is pulled LOW during reset.
