FAQ NO : 105167 Issue Date : Jan.09.13 Functions : Bus State Controller/External Bus Interface , I/O Port When using memory expansion mode, can I use a bus control pin as I/O ports? The bus control pins cannot be used as I/O ports in memory expansion mode or microprocessor mode. However, pins not used for bus control can be used as I/O ports in the following situations. (In the case of the M16C/65C) Pins P1_0 to P1_7 when the da...

FAQ NO : 102411 Issue Date : Jun.28.12 Functions : CPU I inserted multiple NOP instructions to set an accurate time interval. Butthis does not provide an accurate time interval (NOP instruction executioncycles X number of instructions). Why is that? M16C Family has a queue buffer which pre-fetches instruction codes while the bus is not busy. Each instruction execution cycle listed in the software manual is a value based on this condition (the instruction is already in the queue buffer). If ...
