7. REGISTERS AND RAM
7.1 Configuration Register -- Index 40h
Power on default [7:0] = 0000, 0001 b
BIT
NAME
READ/WRITE
DESCRIPTION
7 INITIALIZATION Read/Write
A one restores power on default value to all registers
except the Serial Bus Address register. This bit clears
itself since the power on default is zero.
6-4 Reserved
Read/Write Reserved
3 DIS_PWROK
Read/Write
Disable Power OK Function. If this bit set to 1, the
PWR_DN# (Pin 6) will keep logical high no mater what
the pwoer VDD or +3.3V drop to the threshold voltage
(4.0v and 2.6v, respectively).
2 Reserved
Reserved
Reserved
1 INT_ Clear
Read/Write
A one disables the SMI# outputs without affecting the
contents of Interrupt Status Registers. The device will
stop monitoring. It will resume upon clearing of this bit.
0 Start
Read/Write
A one enables startup of monitoring operation, a zero
puts the part in standby mode.
Note: The outputs of Interrupt pins will not be cleared if
the user writes a zero to this location after an interrupt
has occurred unlike "INT_Clear'' bit.
