(3) Notes on setting display frequency
RSEL1
Whenever setting display frequency (when EXCK1 = "0",
EXCK0 = "1", or EXCK1 = "1", EXCK0 = "1"), always set the
display frequency range in accordance with the display
frequency. This range is set from DIVS0, DIVS1, DIVS2,
RSEL0 and RSEL1 (address 120
given here below.
To change external clock (display) frequency or horizontal syn-
chronization frequency, always use the following procedures.
To set EXCK1 = "0", EXCK0 = "1"
To set EXCK1 = "1", EXCK0 = "1"
