Figure 7-8. SPI Write Frame
Note that while the read frame can be variable in length due to the different length registers in the INA239
device, the write frame is fixed in length as all writable registers are 16 bits wide. During an SPI write frame,
while new data is shifted into the INA239 register, the old data from the same register is shifted out on the MISO
line.
The first 8-bits of each SPI frame are presented in Table 7-2, which shows access to a certain register address
on the MOSI line as well as read/write functionality. On an SPI read operation, the INA239 returns the data read
in the same SPI frame.
