Field
Description
Start
Driven to 1.
R/W
If set to 1, the SPI Master wishes to read from the slave. If set to 0, the SPI Master wishes to
write to the slave.
Addr
If set to 1, a read operation will return the status byte in the data phase. A write will have no
effect.
If set to 0, a read or a write will operate on the data register.
D7:D0
Data.
Status
When 0 this means a read or write was successful. When 1 it means a read contains old data,
or a write did not work and needs retried.
Table 6.7 SPI Command and Status Fields
6.3.6.1 SPI Setup Bit Encoding
The VNC1L compatible SPI interface differs from most other implementations in that it uses a 12 clock
sequence to transfer a single byte of data. In addition to a Start state, the SPI master must send two
setup bits which indicate data direction and target address. The encoding of the setup bits is shown in
Table 6.8. A single data byte is transmitted in each SPI transaction, with the most significant bit
transmitted first.
After each transaction VNC2 returns a single status bit. This indicates if a Data Write was successful or a
Data Read was valid.
