Setting procedure processor mode bits
No.M16C-71-0105
Classification Corrections supplementary explanation document Notes Knowhow Others
Products Effected
M16C/80 Series M16C/60 Series
Precautions
Processor mode bits allocated bits processor mode register Regardless level CNVSS pin, changing processor mode bits selects mode. Therefore, never change processor mode bits when changing contents other bits. change processor mode bits simultaneously with other bits when changing processor mode bits "012" "112". Change processor mode bits after changing other bits. Figure shows processor mode register M16C/62A group, figure shows setting procedure processor mode bits.

Note protect register (address 000A16) when writing values this register. Note voltage applied CNVSS, value this register when reset 0316. (PM00 PM01 both "1".) Note Valid microprocessor memory expansion modes. Note entire space multiplexed memory expansion mode, choose 8bit width.The processor operates using separate after reset revoked, entire space multiplexed cannot chosen microprocessor mode. become port entire space multiplexed chosen, only bytes used each chip select.
