ZDI-Supported Protocol
ZDI allows reading and writing of most internal registers without disturbing the state of
the machine. Reads and writes to memory may occur as fast as the ZDI can download and
upload data, with a maximum frequency of one-half the CPU system clock frequency.
Table 92
clock.
Table 92. Recommended ZDI Clock vs. 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 ini-
tiates the data transfers and provides the clock for both receive and transmit operations.
The ZDI block on the eZ80F92 device is considered a slave in all data transfers.
