users follow the Write Byte protocol exactly, the new data
contained in the Data Byte is written into the register
selected by bits r1 and r0 on the Stop Bit.
General Purpose Input/Outputs (GPIOs)
The LTC4306 provides two general purpose input/output
pins (GPIOs) that can be configured as logic inputs, open-
drain outputs or push-pull outputs. The GPIO1 and GPIO2
Mode Configure bits in register 2 determine whether the
GPIOs are used as inputs or outputs. When the GPIOs are
used as outputs, the GPIO1 and GPIO2 Output Mode
Configure bits of register 2 configure the GPIO outputs
either as open-drain N-channel MOSFET pull-downs or
push-pull stages.
In push-pull mode, at VCC = 3.3V, the typical pull-up
impedance is 670Ω and the typical pull-down impedance
