FAQ NO : 1000173 Issue Date : Sep.21.10 Functions : I/O Port , Pin When switching a pin function or the operating mode of a peripheral function, a pulse is output momentarily from the pin. Why? In general, when a pin function or the operating mode of a peripheral function is switched, due to the margin of delay in the switching signal of the internal switching circuit, a short pulse of several ns may be output before the function or operatin...

FAQ NO : 107393 Issue Date : Jun.12.09 Functions : I/O Port What values of external capacitance can be added to the ports ? (1) CMOS3 State I/O Ports When adding external capacitance, select approximately 30 pF (Note). Note: Value used during measurement of timing characteristics by Renesas. Please perform evaluations for your system to determine an appropriate capacit... Relevant Products R8C/1x R8C/2x R8C/3x R8C/Lx R8C/Mx M16C Family (R32C/M32C/M16C)
FAQ NO : 106019 Issue Date : Apr.24.06 Functions : Interrupt/Exception Handling Key input interrupt occurs on the falling edge of the input signal. When key input which continues "L" level input after the falling edge is generated, is key input in the meantime detected? If input signal falls once and then "L" level input continues, the key input after the second is not detected.

FAQ NO : 106021 Issue Date : Apr.24.06 Functions : Other Timer/Pulse Function When the counter stops after outputting the pulse in the pulse output modeof Timer A, is the output level undefined ? It depends on the mode of Timer A. In Timer Mode: It outputs "L" during counter stop. In Event Counter Mode: It outputs "L" during counter stop. In One-shot Timer Mode: It outputs "L" during counter stop. It outputs "H...
