INA740A: read 24bit and 40bit

Hey Benno,

Once you set the register pointer to desired register address, you simply initiate a read command, and then the whole contents of the register will be sent in 8 bit (1 byte) chunks until finished. You can see how we read these variable sized registers with our provided EVM code seen in our Sys Config tool:

https://dev.ti.com/sysconfig/index.html#/config/?args=--product%20%2Fmnt%2Ftirex-content%2Fascstudio_1_0_13%2F.metadata%2Fproduct.json%20--device%20Other&module=%2Fti%2Fsensors%2Fcurrentsensor%2FINA740 

The datasheet shows a read command for a 2 byte register, but for a larger register the INA740 would continue transmitting bytes until the whole register was sent.

Sincerely,

Peter
