Whether the BEEP alarm function is enabled or disabled is determined by the control bit at Hardware
Monitor Device, Bank 0, Index 57h, bit 7. Also, each event has their individual enable bit at Hardware
Monitor Device, Bank 0, Index 56h bit [7:0], Index 57h bit [6:0] and Bank 4, Index 53h, bit [1:0].
BEEP/SO is an open-drain output pin and its default state is low. When the BEEP alarm function is
activated, this pin repeatedly outputs 600 Hz square wave for 0.5 second and 1.2 KHz square wave
for 0.5 second in turn until the enable bit or the abnormal event is cleared.
