Product Specification
11.15 LCD Driver
11.15.1 Overview
The LCD driver is controlled by the LCD Control Register (LCDCRH/L). The LCLK[1:0] determines the
frequency of COM signal scanning of each segment output. A RESET clears the LCD control register LCDCRH
and LCDCRL values to logic ‘0’.
The LCD display can continue operating during IDLE and STOP modes if a sub-frequency clock is used as
system clock source.
