CHAPTER 10 CLOCK OUTPUT CONTROL CIRCUITS

10.1 Clock Output Control Circuit Functions

The clock output control circuit is intended for carrier output during remote controlled transmission and clock output
for supply to peripheral LSIs. The clock selected with the clock output selection register (CKS) is output.
Figure 10-1 shows the block diagram of clock output control circuits.
