25.2.1
This LCDC can select the bus clock (Bφ), the peripheral clock (Pφ), or the external clock as its
operation clock source. The selected clock source can be divided using an internal divider into a
clock of 1/1 to 1/16 and be used as the LCDC operating clock (DOTCLOCK). The clock output
from the LCDC is used to generate the synchronous clock output (CL2) for the LCD panel from
the operating clock selected in this register. The average frequency of CL2 can be calculated using
the formula below. The actual frequency, however, will differ depending on the type of LCD panel
and the bus width of the data output to the LCD panel. See section 25.4, Clock and LCD Data
Signal Examples, for details.
Set this register so that the clock input to the LCDC is 50 MHz or less regardless of CL2.
Bits 15, 14, and 11 to 5—Reserved
Bits 13 and 12—Input Clock Select (ICKSEL1 and ICKSEL0): Set the clock source for
DOTCLOCK.
