• Output Limit (bit5,bit6:NSLMT1 ,NSLMT2 )

The M65818AFP has Over Flow Limit function which detects by input signal level and limit gain control.

Limit value is set by Gain Control Mode :bit5,bit6 ”NSLMT1, NSLMT2” and System2 Mode:bit17"NSOBIT".

The limit value setting of Gain control block and PWM output.
