(4) Application to remote control output
The clock output function of the PD75238 is applicable to remote control output. The frequency of the
carrier for remote control output is selected by the clock frequency select bit of the clock output mode
register. Pulse output is enabled or disabled by controlling the clock output enable/disable bit by software.
The clock output circuit is designed so that pulses with short widths do not appear in enabling or disabling
clock output.
