■ DSP Programmable Output
The DSP block has two General Purpose Output (GP0 and GP1) pins for external device controlling. The outputs can be
controlled by DSP programs. SELDO3 and SELDO4 bits control SDOUT3/GP0 and SDOUT4/GP1 pins respectively.
OUT3N and OUT4N bits switch output enable/disable of these. When controlling the GPCby the GP0 and GP1 pins, the
initial state of the GP0 and GP1 pins are “L”.
