(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
This OSD clock for each block can be selected by the following bits
: bit 7 of the port P3 direction register, bits 5 and 4 of the clock source
control register (addresses 0216
16
). A variety of character sizes can
be obtained by combining dot sizes with OSD clocks. When not us-
ing 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 P6.

Note :
Be sure to set bit 7 to “0” for program of the mask and the
EPROM versions. For the emulator MCU version
(M37270ERSS), be sure to set bit 7 to “1” when using the
data slicer clock for software debugging.
