PRTxDM1
21.4.2
This register is one of three registers where the combined value determines the unique drive mode of each bit in a GPIO port.
In register PRTxDM1 there are four possible drive modes for each port pin. Two mode bits are required to select one of these
modes, and these two bits are spread into two different registers (PRTxDM1 and
the effected port pin (for example, Pin[2] in Port 0) is the same as the bit position of each of the two Drive Mode register bits
that control the drive mode for that pin (for example, bit[2] in PRT0DM0 and bit[2] in PRT0DM1). The two bits from the two
registers are treated as a group. These are referred to as DM1 and DM0, or together as DM[1:0].
All drive mode bits are shown in the sub-table below ([ 1 0] refers to the combination (in order) of bits in a given bit position);
however, this register only controls the most significant bit (MSb) of the drive mode.
The upper nibble of the PRT4DM1 register returns the last data bus value when read. You need to mask it off before using
this information. For additional information, refer to the
