Pin Descriptions
In order to maximize the NUC501 application for different field, each pin of NUC501 is very flexible
and can play up to four different functions. The user can program each pin to the wanted function for the
different product.
The pin functions are controlled by the registers PAD_REG0, PAG_REG1 and PAD_REG2. For each
multiple function pin, the default function is the GPIO. When the user programs the PAD_REG, the pins
play the alternative function. If the different alternative functions are enabled simultaneous, the priority is
Alternative Function 1 > Alternative Function 2 > Alternative Function 3 > Default Function
For example:
If the GPA[12] is configured to be SPIMS_SO by PAD_REG1 and it is also configured to be PWMT0 by
PAD_REG0, the actual function of GPA[12] would be SPIMS_SO because the SPIMS_SO function priority is
higher than PWMT0.
Except the multiple functions, each NUC501 output driving current strength is also controllable. The
driving strength control register is the GPA_DS, GPB_DS and GPC_DS. For different pin the driving can be
4mA or 8mA and 12mA or 16mA. For example, user can control the GPB[1] strength to 16mA and directed
drive the high current LED to save PCB extra component to reduce the BOM cost.
