12.11.4 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)
Clock from the LC oscillator supplied from the pins OSC1 and OSC2
Clock from the ceramic resonator or the quartz-crystal oscillator
from the pins OSC1 and OSC2
The clock for display to be used for OSD can be selected by bit 7 of
port P3 direction register, bit 2 and bit 1 of clock source control reg-
ister (address 021616). If the pins OSC1 and OSC2 are not used as
OSD clock input/output, these pins can be used as the sub-clock
input/output, or port P6.

Note 1: Set bit 7 of address 00C716 to “1”, when OSC1 and OSC2 are used as P63
and P64.
2: Be sure to set bit 7 to “0” for program of the mask and the EPROM versions.
For the emulator MCU version (M37280ERSS), be sure to set bit 7 to “1”
when using the data slicer clock for software debugging.
