MUX Control Register (MCR)
STMPE2403 is integrated with 2 SPDT bi-directional signal multiplexer. The Ron of the
multiplexer is 5 OHM (Typical). Signal level is 1.8V (MAX). The MUX are controlled by the
MUX Control register.
MCR is to control the two analog multiplexers operation.

MUX 1 Control 0 bit selects whether Mux1In_0 or Mux1In_1 connects to
Mux1Out.
‘0’ – Mux1In_0 is connected to the Mux1Out.
‘1’ – Mux1In_1 is connected to the Mux1Out.
MUX 1 Control 1 bit enables the MUX 1.
‘0’ – Enables the MUX 1.
‘1’ – Disables the MUX 1.
MUX 2 Control 0 bit selects whether Mux2In_0 or Mux2In_1 connects to
Mux2Out.
‘0’ – Mux1In_0 is connected to the Mux1Out.
‘1’ – Mux1In_1 is connected to the Mux1Out.
MUX 2 Control 1 bit enables the MUX 2.
‘0’ – Enables the MUX 2.
