Key-scanning and display timing
During the first cycle, the 16 channels are used for the keyscan. The keyscan duration is
made up of 64 µs. The second cycle is used for the display of the LED (discrete). The
maximum time is 512µs and the 3
number of cycles will increase or decrease depending upon the user configuration.
By default, the configuration is made up of 4 cycles. If any data is written to the discrete
LED, only then the 2
