The CLCDC clock (from the RCPC) is scaled within the CLCDC and used to produce the LCDDCLKoutput. CLCDC registers set timing (in terms of LCDDCLK pulses) to produce the other signals thatcontrol an STN display.2. The duration ot the LCDLP signal is controlled by Timing0:HSW (the HSW bit field in the Timing0 Register).3.
