LTC1840 Device Addressing
It is possible to configure the part to operate with any one
of nine separate addresses through the three state A0 and
A1 pins. Table 1 shows the correspondence of addresses
to the states of the pins:

For the A0 and A1 lines, L refers to a grounded pin, H is a
pin shorted to V
CC
and NC is no connect. The pin voltage
will be set to approximately V
CC
/2 when not connected.
Bits B7, B6 and B5 of the address are hardwired to 111.
Register Addresses and Contents
Fault conditions are cleared by the action of writing to the
fault register, but the data byte from the write command is
not actually loaded into the register.
A TACHA/B FLT (fault) bit will be high if the corresponding
TACHA/B FLTEN bit in the status register has been set high
and the corresponding TACHA/B counter has overflowed
its maximum count of 255. These faults are latched
internally and must be cleared by writing to the fault
register or by setting TACHA/B FLTEN low. The fault will be
reasserted if the counter is still in overflow after a write to
the fault register. The TACH FLT bits power-up in the low
state.
The blast and timer bits become high after blasting and
serial access time-out events, respectively.
A high GPIOX FLT bit reflects that the GPIOX pin has
caused a fault condition; to do so, the pin must be enabled
as fault producing in the GPIO setup register (GPIOX
FLTEN set high) and the logic state of the pin must change
after the enable. The fault is latched internally and must be
cleared through software by writing to the fault register or
by setting GPIOX FLTEN low; a change in the state of the
GPIOX pin from its state at the point of the fault register
being written will cause another fault to be signalled.
