Registers 85h-88h: A/D Converter LSbs Registers
There is a 10-bit Analog to Digital Converter (ADC) located in the hardware monitoring block that
converts the measured voltages into 10-bit reading values. Depending on the averaging scheme
enabled, the hardware monitor may take multiple readings and average them to create the values
stored in the reading registers (i.e., 16x averaging, 32x averaging, etc.) The 8 MSb’s of the reading
values are placed in the Reading Registers. When the upper 8-bits located in the reading registers
are read the 4 LSb’s are latched into their respective bits in the A/D Converter LSbs Register. This
give 12-bits of resolution with a minimum value of 1/16
-127.9375 ºC < Temp < 127.9375 ºC and Voltage Range: 0 < Voltage < 256.9375) . See the DC
Characteristics for the accuracy of the reading values.
The eight most significant bits of the 12-bit averaged readings are stored in Reading registers and
compared with Limit registers. The Interrupt Status Register bits are asserted if the corresponding
measured value(s) on the inputs violate their programmed limits.
Register 89h: SMSC Test Register
Registers 8Ah: SMSC Test Register
Registers 8Bh: SMSC Test Register
This register becomes read only when the Lock bit is set. Any further attempts to write to this register
shall have no effect.
This register must not be written. Writing this register may produce unexpected results.
