7
CR2
This bit along with Bits CR1and CR0 determines the serial clock frequency when SIO is
in the Master Mode.
6
ENII
Enable IIC. When ENI1 = 0, the IIC is disabled. SDA and SCL outputs are in the high
impedance state.
5
STA
START Flag. When this bit is set, the SIO H/W checks the status of the I
2
C-bus and
generates a START condition if the bus free. If the bus is busy, the SIO will generate a
repeated START condition when this bit is set.
4
STO
STOP Flag. With this bit set while in Master Mode a STOP condition is generated.
When a STOP condition is detected on the I
2
C bus, the I
2
C hardware clears the STO
Flag.
Note:
This bit have to be set before 1 cycle interrupt period of STOP. That is, if this bit is
set, STOP condition in Master Mode is generated after 1 cycle interrupt period.
3
ADDR
This bit is set when address byte was received. Must be cleared by software.
2
AA
Acknowledge enable signal. If this bit is set, an acknowledge (low level to SDA) is
returned during the acknowledge clock pulse on the SCL line when:
Own slave address is received
A data byte is received while the device is programmed to be a Master Receiver
A data byte is received while the device is a selected Slave Receiver. When this bit is
reset, no acknowledge is returned.
SIO release SDA line as high during the acknowledge clock pulse.
1
CR1
These two bits along with the CR2 Bit determine the serial clock frequency when SIO is
in the Master Mode.
