(7) Clock control register MR
Register MR controls system clock and operation mode
(frequency division of system clock). Set the contents of this
register 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.
(8) Clock control register RG
Register RG controls the start/stop of each oscillation circuit. Set
the contents of this register through register A with the TRGA
instruction.
Note 1. R” represents read enabled, and “W” represents write enabled.
Note 2. The stopped clock cannot be selected for system clock.
Note 3. “11” cannot be set to the low-order 2 bits (MR1, MR0) of register MR.
Note 4. The oscillation circuit selected for system clock cannot be stopped.
