PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
ROM ORDERING METHOD
1.Mask ROM Order Confirmation Form
2.Mark Specification Form
3.Data to be written to ROM, in EPROM form (three identical cop-
ies) or one floppy disk.
For the mask ROM confirmation and the mark specifications, re-
fer to the “Renesas Technology Corp.” Homepage

(7) Clock control register MR
Register MR controls 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.
