L9369 registers, its feature is CR: Clear on Read

Read such register,  all 16 bits of this register will be changed to the Default status, right?

Yes, if a register in the L9369 has the CR (Clear on Read) feature, then reading the register will reset all 16 bits of that register to its default status. Once you read the register, the current value will be retrieved. Immediately after reading, all bits will be cleared or reset to their default state as defined in the datasheet.

Before register value change to default value by reading, the effective value can still be read out by MCU host, right?

Thanks!
