If a repeated START condition has been transmitted then the
status code will be 10
H
instead of 08
H
.
2. Transmit Slave Address and Write
The I2C_DATA register
should now be loaded, with the address of the slave to be written
to in bits[7:1] and bit[0] cleared to zero to specify Write. The IFLG
bit should now be cleared to zero before the transfer can
continue. When the slave address and write bit have been
transmitted and an acknowledqe bit received the IFLG will be set
again. A number of status codes are now possible in the STAT
register, as shown in Tables 47 and 48.
3. Transmit Data
If the code 18
or 20
has been detected in the
STAT, the next byte to be placed in the I2C_DATA register is the
first data byte, or a word address in the case of some memory
devices. The IFLG can then be cleared. After each additional
data byte has been transmitted the IFLG will be set and one of
three status codes will be in the START register, as shown in
Tables 49 and 50.

1. Transmit Start Condition.
The master transmit mode is
entered by settinq the STA bit to one. The ACE9050 I
2
C will then
test the I
2
C bus and will transmit a START condition when the bus
is free. When a START condition has been transmitted the IFLG
bit will be set and the status code in the STAT register will be 08
