Move/Read Operation
The Move/Read operation simultaneously reads the
contents of a data register and moves the contents into
the corresponding DCP’s WCR. If more than one data
register byte is read, then all wipers accessed will have
their WCR’s updated with the data register values that
were read. Move/Read operation consists of a one
byte, or three byte instruction followed by one or more
Data Bytes (See Figure 9). To read an arbitrary byte,
the master initiates the operation issuing the following
sequence: a START, the Slave Address byte with the
R/W bit set to “0”, an Address Byte, a second START,
and a second Slave Address byte with the R/W bit set
to “1”. After each of the three bytes, the X9455
responds with an ACK. Then the X9455 transmits Data
Bytes as long as the master responds with an ACK
during the SCL cycle following the eighth bit of each
byte. The master terminates the Move/Read operation
(issuing a STOP condition) following the last bit of the
last Data Byte.
The first byte being read is determined by the current
wiper address and by the Status Register bits,
according to Table 1 on page 11. If more than one byte
is read, the WCR address is incremented by one after
each byte, in the same way as during a Page Write
operation. After reaching WCR0B, the WCR address
“rolls over” to WCR0A.
On power up, the Address pointer is set to the Data
Register 0 of WCR0A.
