SNAS465D –SEPTEMBER 2009–REVISED MARCH 2013

Bit Name Read/Write Description

4-7 Temp [3:0] Read/Write The lower nibble (4 LSbs) of the 11-bit plus sign temperature data:

<4> = Temp [0] (nibble LSb, 0.0625°C),

<5> = Temp [1],

<6> = Temp [2],

<7> = Temp [3] (nibble MSb, 0.5°C).

For 8-bit plus sign temperature resolution:

<7> = Temp [0] (LSb, 0.5°C)

<4:6> are undefined

Conversion Rate Register—Address 07h

Power on default <7:0> = 0000 0000 binary

Bit Name Read/Write Description

0 CR1 Read/Write Controls conversion rate:

0 = 728ms (typical)

1 = Continuous Conversion.

Note:

— Each voltage channel conversion takes 3 ms typical.

— Temperature conversion takes 3.6 ms typical for 9 - bit resolution and 23.5 ms typical for 12

- bit resolution.

— Each fan tachometer input is monitored for 2 pulses, the time interval for two pulses is added

to the round robin time for each fan tach input that is enabled.

1-7 Reserved Read only Reserved — will always report zero.

Voltage/Temperature Channel Disable Register—Address 08h

Power on default <7:0> = 0000 0000 binary

Bit Name Read/Write Description

0 IN0 Read/Write When set to "1", IN0:

conversions are skipped and disabled

value register reading will be 0
