9-bit video input processor
SAA7113H
Table 22 Description of I2C-bus format; note 1
Notes
1. The SAA7113H supports the ‘fast mode’ I2C-bus specification extension (data rate up to 400 kbits/s).
2. If more than one byte DATA is transmitted the subaddress pointer is automatically incremented.
CODE
DESCRIPTION
S
START condition
Sr
repeated START condition
Slave address W
0100 1010 (= 4AH, default) or 0100 1000 (= 48H, if pin RTS0 strapped to ground via a 3.3 k
resistor)
Slave address R
0100 1011 (= 4BH, default) or 0100 1001 (= 49H, if pin RTS0 strapped to ground via a 3.3 k
resistor)
ACK-s
acknowledge generated by the slave
ACK-m
acknowledge generated by the master
Subaddress
subaddress byte; see Table 24
Data
data byte; see Table 24; note 2
P
STOP condition
X = LSB slave
address
read/write control bit; X = 0, order to write (the circuit is slave receiver); X = 1, order to read
(the circuit is slave transmitter)
