As shown in the diagram below, delay time of 0 to 127 pulses of the LCP0 clock can be
inserted in the LLOAD signal.
Delay time = <LDD6:0>
Note: The delay time for the LLOAD signal is controlled based on LCDLDDLY<PDT>=1. Therefore, even if the
delay time is set to”0” with LCDLDDLY<PDT>=0, the LLOAD signal is output with a delay of one LCP0
clock. Be careful about this point.
