R8C/14 Group, R8C/15 Group 5. Electrical Characteristics

Timing requirements (Unless otherwise specified: V

CC = 3V, VSS = 0V at Topr = 25 °C) [VCC = 3V]

NOTES:

1. When using the Timer C input capture mode, adjust the cycle time (1/Timer C count source frequency x 3) or above.

2. When using the Timer C input capture mode, adjust the width (1/Timer C count source frequency x 1.5) or above.

NOTES:

1. When selecting the digital filter by the INT0

input filter select bit, use the INT0 input HIGH width to the greater value, either

(1/digital filter clock frequency x 3) or the minimum value of standard.

2. When selecting the digital filter by the INT0

input filter select bit, use the INT0 input LOW width to the greater value, either

(1/digital filter clock frequency x 3) or the minimum value of standard.
