Why same name of TPU at output pins No.34 ~ 35 are added?

Latest Updated:03/19/2009

Question:

Same name of TPU outputting at output pins No.34 ~ 35 are added on multiple output pins. (TIOCA3,TIOCC3,TIOCA4,TIOCA5,TIOCA0,TIOCC0,TIOCA1,TIOCA2)

Answer:

The reason why TIOCAn/TIOCBn are assigned at the same pin is to enable users to use input catpure respectively.

The case of TIOCAn assigned at the pins alone is the pin arrangement of using TIOCAn/TIOCBn for input capture independently each other. Hence when the inputs of TIOCAn/TIOCBn using at same pins, the pins TIOCAn assigned can be used as I/O port(but not used as input of input capture).
