HOW TO USE THE FUNCTIONS
If CNTSEL is “L”, the above functions are valid. (CNTSEL is “H” or open, default values are valid.) After serial data
are transferred, the data is latched by CNTSTB. Once, the data is latched, the above functions are effective.
Please keep CNTSTB to be “L” during transferring data. Input data can be changed during power on, but LCD display
may be disturbed. When the serial data are changed, we recommend that the backlight power is off using BRTC
function.
