REGISTER BIT MAPS
The SML2108 has three user programmable, nonvolatile
configuration registers.
Register 0
This register is used to configure the 8-Bit ADC that
monitors the bias current. Bit 7 enables the ADC alert to
be latched, which will hold the ALERT pin low until the alert
is reset. Bits 6, 5, and 4 are used to set the sample interval
of the ADC. The input to the ADC can be scaled and offset
to provide maximum resolution over the bias current. Bits
3 and 2 are used to set the full scale range of the ADC,
while bits 1 and 0 are used to set the ADC offset. See the
Table.
Register 1
This register controls multiple functions. Bit 7 disables the
alert during a manual analog-to-digital conversion of the
bias current. Bit 6 selects the action that will reset an alert
from the ADC. When this bit is set to a 0 any device read
or write will reset the alert. When set to a 1 the alert will be
reset by a low AUTOMON signal. Bit 5 is used to toggle
the source of the ADC input between the I
BIAS
current and
the EXT TEMP signal. Bit 2 initializes the input of the 10
bit DAC to either zero or a stored value from a nonvolatile
register when the device is powered up. Bit 1 initializes the
input of the 8 bit DAC to either zero or a stored value from
a nonvolatile register when the device is powered up. Bit
0 sets the maximum P-channel bias current (I
BIASP
) and
modulation current (I
MODP
) to either 10mA or 100mA.
Register 2
This register controls several functions related to the bus
interface. Bits 7 and 6 control the read and write access
to the configuration registers. It is imperative that register
2 be programmed properly to prevent an inadvertent
lockout. Bit 5 determines whether the memory array is
available or locked. Bit 4 selects the device type address
for accessing the memory array, while bit 3 determines
whether the device must receive a bus address that
corresponds to the biasing of the address pins. Bit 2 is
used to enable an alert condition on the ADC to shut down
the bias current. Bits 1 & 0 are unused.
