CLOCK OUTPUT CIRCUIT
The clock output circuit is used for outputting the clock pulse from the P22/PCL pins. It is used, for example,
when a clock pulse is to be output to the remote control output, peripheral LSI, etc..
Clock output (PCL) :
Φ
, 524, 262, 65.5 kHz (4.19 MHz operation)
The configuration of the clock output circuit is shown below.
Fig. 5-2 Clock Output Circuit Configuration
Remark
Consideration is given so that a low-amplitude pulse is not output when switching between clocks.
