External clock (CLK_IN) frequency input level When using external clock (CLK_IN) input, input frequency equal internal oscillation frequency +20% more CLK_IN. addition, CLK_IN configuration shown figure "CLK_IN (input) equivalent circuit (outline)" below. 0.8V reference voltage CLK_IN compared determine edges, input signal 0.8V more (VCC voltage less) external clock (CLK_IN). External/internal clock switching before switching between external clock internal clock. Maximum duty maximum duty (Duty_MAX*) channel channel (typ.) setting. When using external clock (CLK_IN), maximum duty (Duty_MAX*) becomes smaller, care must taken output voltage. (CLK_IN (input) equivalent circuit (outline))

When protection circuit (SCP) operates, channel outputs turned OFF. When using protection function (SCP), must shorted GND_S with line that short possible. When function operates SCP_OUT goes High, outputs latched OFF. This latched state canceled setting turning power supply off.
