DATASHEET
Bits[7:0] This location contains the identification number which will
be used by software to determine analog voltage curves.
Bits[7:0] This location contains the stepping number of the part in
the lower four bits of the register [3:0]. The upper four bits reflect
the Version Number [7:4]. The Hardware Monitor Block has a
version number (Bits[7:4]) of 0010.
Hardware Monitor Block, this register will read 0010 0000.
Bit[0] Start
Logic 1 enables startup of monitor block, logic 0 places the block
in the low power mode selected by bit 0 of the Special Function
register at 4Fh. At startup, limit checking functions and scanning
begins. Note, all HIGH and LOW LIMITS should be set into the
ASIC prior to turning on this bit.
Bits[3:1] Reserved
Bit[4] Reset
Setting this bit generates a minimum 20 ms low pulse on the
Reset pin, if the function is enabled. (See VID Register).
This bit is self-clearing.
Bit[5] +12/VID4 Select
Selects whether pin 10 acts as a 12 Volt Analog Input monitoring
pin, or as a VID[4] input. This pin defaults to the 12 Volt Analog
Input.
Bit[6] Reserved
Bit[7] Initialization
Logic 1 restores powerup default values to the Configuration
Register and Interrupt status registers. This bit automatically
clears itself since the power on default is zero.
