For ADIS16497, each register is byte accessible. If I want to configure the device, do I need to send two commands to write to both the lower byte higher byte of the register for the configuration to take effect?
For example, if I want to toggle a bit in FNCTIO_CTRL, I only need to write to the lower byte, since the bit I want to toggle is in lower byte. Do I have to write to the higher byte as well?
If I need to write to both bytes of FNCTIO_CTRL for configuring the device, do I need to stall for long period of time for both writes? (the datasheet specifics 340us for FNCTIO_CTRL.)
