clock.
Table 89. Recommended ZDI Clock versus System Clock Frequency
ZDI supports a bidirectional serial protocol. The protocol defines any device that sends
data as the transmitter and any receiving device as the receiver. The device controlling the
transfer is the master and the device being controlled is the slave. The master always
initiates the data transfers and provides the clock for both receive and transmit operations.
The ZDI block on the eZ80L92 MCU is considered as slave in all data transfers.
