Time-out alert of GCLK disconnection
When the PWCLK signal is disconnected for around 1 second, all output ports will be turned
off automatically. This function will protect the LED display system from staying ON
indefinitely and prevent excessive current from damaging the power system. The default is
set to ‘enable” when bit “0” of the Configuration Register is 0. When the PWCLK is active
again and new serial data are moved in, the driver resumes to work after resetting the
internal counters and comparators.
