Single-chip 16/32-bit microcontrollers
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.
Settings other than those shown in the table are reserved, and should not be used.
