LV24230LP
No.A0891-7/17
LV24230 latches ACK at the rising edge.
The sequence to write data D into the register A of LV24230 is shown below.
Start condition
write the device address (C0h)
write the register address, A
write the target data, D
stop condition
Fig. 4 Register write through I2C
When one or more data has been provided for writing, only the first data is allowed to be written.
Read sequence
start condition
write the device address (C0h)
write the register address, A
repeated start condition (or stop + start in a single master network)
write the device address + 1 (C1h)
read the register contents D, transmit NACK (no more data to be read)
stop condition

Interrupt Pin INT
LV24230 has the dedicated interrupt output pin. For the active level to the host, either LOW or HIGH can be selected.
The INT output pin is kept floating while the PWRAD bit is cleared during initialization.
Therefore, to avoid influence on the CPU side during initialization, it is recommended to secure the non-active state by
means of the pull-up or pull-down resistor.
This enables direct INT output connection to non-masking interruption of the host CPU.
