ZSC31010 Read Operations

The incoming frame will be checked for proper parity on both, command and data bytes, as well as for any edge

time-outs prior to a full frame being received.

Once a command/data pair is received, the ZSC31010 will perform that command. After the command has been

assume the command was either improperly received or could not be executed.

Read Acknowledge

The ZSC31010 transmits 10-bit bytes (1 start bit, 8 data bits, 1 parity bit). During calibration and configuration,

different digital output modes configurable (digital output with temperature, and digital output with only bridge

data). During Normal Operation Mode, if the part is configured for digital output of the bridge reading, it first

transmits the high byte of bridge data, followed by the low byte. The bridge data is 14 bits in resolution, so the

upper two bits of the high byte are always zero-padded. There is a 32

μs stop time when the bus is held high

between bytes in a packet.
