Description
Frame Frequency Select 3 to 0
Bits 3 to 0 select the operating clock and the frame
frequency. In subactive mode, watch mode, and subsleep
mode, the system clock (φ) is halted, and therefore
display operations are not performed if one of the clocks
from φ/16 to φ/2048 is selected. If LCD display is required
in these modes, φ
the operating clock.
