7.1 OUTPUT_PORT
OUTPUT_PORT: 04h
This register is used to write data to DIG output port. Pins defined as output of combinational logic (in OP_SEL_x register) cannot be
changed using this register.
7.2 CS_ENABLE
CS_ENABLE: 07h
(
This register is used to enable CapSense inputs. This register should be set before setting finger threshold (0x66, 0x67) and
IDAC setting (0x70, 0x71) registers.
