C Read and Write Operations
Table 6 shows the timing of a single word write operation. Every
ninth clock, the ADAV400 issues an acknowledge by pulling
SDA low.
Rev. 0 | Page 16 of 36
Table 7 shows the timing of a burst mode write sequence. This
table shows an example where the target destination registers are
two bytes. The ADAV400 auto-increments its subaddress
register counter every two bytes until a stop condition occurs.
The timing of a single word read operation is shown in Table 8.
Note that the first R/W bit is still a 0, indicating a write operation.
This is because the subaddress must be written to set up the
internal address. After the ADAV400 acknowledges the receipt
of the subaddress, the master must issue a repeated start command
followed by the chip address byte with the R/W set to 1 (read).
The ADAV400 responds with the read result on SDA. The
master then responds every ninth clock with an acknowledge
pulse to the ADAV400.
Table 9 shows the timing of a burst mode read sequence. This
table shows an example where the target read registers are two
bytes. The ADAV400 increments its subaddress register every two
bytes because the requested subaddress corresponds to a
register or memory area with word lengths of two bytes. Other
address ranges may have a variety of word lengths ranging from
one to six bytes; the ADAV400 always decodes the subaddress
and sets the auto-increment circuit so that the address
increments after the appropriate number of bytes.
Key for Table 6 to Table 9:
S = start bit
P = stop bit
AM = acknowledge by master
AS = acknowledge by slave
