8.11.3 Clock for OSD
As a clock for display to be used for OSD, it is possible to select one
of the following 3 types.
Data slicer clock output from the data slicer (approximately 26 MHz)
OSC1 clock supplied from the pins OSC1 and OSC2
Clock from the ceramic resonator or the LC oscillator from the pins
OSC1 and OSC2
This OSD clock for each block can be selected by the following bits
: bit 7 of the raster color register (address 00D916), bits 3 to 6 of the
clock source control register (addresses 00D016). A variety of char-
acter sizes can be obtained by combining dot sizes with OSD clocks.
When not using the pins OSC1 and OSC2 for the OSD clock I/O
pins, the pins can be used as sub-clock I/O pins or port P2.
