8. Low Power Reset (LVR) & Watchdog Timer
When the voltage level of power supply is below 4.0V for a specific time, the LVR will generate a chip reset
signal. After the power supply is above 4.0V, LVR maintain in reset state for 144 Xtal cycle to guarantee the
chip exit reset condition with a stable X'tal oscillation.
The WatchDog Timer automatically generates a device reset when it is overflow. The interval of overflow is
0.25 sec x N, where N is a number from 1 to 8, and can be programmed via register WDT(2:0). The timer
function is disabled after power on reset, user can activate this function by setting WEN, and clear the timer
by set WCLR.
9. A/D converter
The MTV212A32 is equipped with three 6-bit A/D converters, S/W can select the current convert channel
by setting the SADC1/SADC0 bit. The refresh rate for the ADC is OSC freq./12288. The ADC compare the
input pin voltage with internal VDD*N/64 voltage (where N = 0 - 63). The ADC output value is N when pin
voltage is greater than VDD*N/64 and smaller than VDD*(N+1)/64.
