CLOCK CONTROL
The clock control circuit consists of the following circuits.
System clock generating circuit
Control circuit to stop the clock oscillation
Fig. 37 Clock control circuit structure
(1) Clock control register
Register MR controls system clock. Set the contents of this regis-
ter through register A with the TMRA instruction. In addition, the
TAMR instruction can be used to transfer the contents of register
MR to register A.
