SLCD TWRPI interface
Table 4
shows TWRPI/TWRPI-SLCD pin-out and corresponding connection to GD-6363P LCD.
TWRPI-SLCD connector is also compatible with other TWRPIs. It can accept touch TWRPI daughter
cards that may feature keypads, rotary dials, sliders, etc. As MKL43Z256 MCU does not support TSI the
only software GPIO method provided in TSS can be used for touch events detection.
