8.4 System Reset (XMODE)
• The LC89075W-H features a built-in power-on reset circuit, and constantly monitors the power supply status.
• When XMODE is set to “H” and the power is turned on, the system is reset by this power-on reset circuit.
• When not using the power-on reset circuit, always set XMODE to “L” to reset the system during power-on. The
system operates correctly when XMODE is set to “H” after the reset sequence. When XMODE is set to “L” again
thereafter, the system is reset.
