ZDI Read Operations
ZDI Address
ZDI Block Write
The Block Write operation is initiated in the same manner as the single-byte Write opera-
tion, but instead of terminating the Write operation after the first data byte is transferred,
the ZDI master can continue to transmit additional bytes of data to the ZDI slave on the
eZ80F92 device. After the receipt of each byte of data the ZDI register address increments
by 1. If the ZDI register address reaches the end of the Write Only ZDI register address

ZDI Single-Byte Read
Single-byte Read operations are initiated in the same manner as single-byte Write opera-
tions, with the exception that the R/W bit of the ZDI register address is set to 1. Upon
receipt of a slave address with the R/W bit set to 1, the eZ80F92 device’s ZDI block loads
the selected data into the shifter at the beginning of the first cycle following the single-bit
data separator. The msb is shifted out first.
