The communication cycle is started by asserting the CS line
and starting the clock from its idle state. To assert a read cycle,
during the instruction phase of the communication cycle, the
Instruction Byte should be set to a read transfer (R/W = 0).
When reading the serial port, data is driven out of the HI7190
on the falling edge of SCLK. Data can be registered
externally on the next rising edge of SCLK.
Detailed Register Descriptions
Data Output Register
The Data Output Register contains 24 bits of converted data.
This register is a read only register.
