Example 1: When f
SYS
= 10 MHz, STN mode, LCDMODE0
Internal reference clock LCP0 = f
SYS
/ 8 = 10 MHz / 8 = 1.25 [MHz]
LCP0 period = 1 / 1.25 [MHz] = 0.8 [
μS]
Example 2: when f
SYS
= 60 MHz, TFT mode, LCDMODE0
Internal reference clock LCP0 = f
SYS
/ 16 = 60 MHz / 16 = 3.75 [MHz]
LCP0 period = 1 / 3.75 [MHz] = 266 [nS]
