I2C BUS INTERFACE (Cont’d)
I2C OWN ADDRESS REGISTER (OAR1)
Read / Write
Reset Value: 0000 0000 (00h)
7-bit Addressing Mode
Bit 7:1 = ADD7-ADD1
Interface address.
These bits define the I2C bus address of the inter-
face. They are not cleared when the interface is
disabled (PE=0).
Bit 0 = ADD0
Address direction bit.
This bit is don’t care, the interface acknowledges
either 0 or 1. It is not cleared when the interface is
disabled (PE=0).
Note: Address 01h is always ignored.
10-bit Addressing Mode
Bit 7:0 = ADD7-ADD0
Interface address.
These are the least significant bits of the I2C bus
address of the interface. They are not cleared
when the interface is disabled (PE=0).
I2C OWN ADDRESS REGISTER (OAR2)
Read / Write
Reset Value: 0100 0000 (40h)
Bit 7:6 = FR1-FR0
Frequency bits.
These bits are set by software only when the inter-
face is disabled (PE=0). To configure the interface
to I2C specifed delays select the value corre-
sponding to the microcontroller frequency FCPU.
Bit 5:3 = Reserved
Bit 2:1 = ADD9-ADD8
Interface address.
These are the most significant bits of the I2C bus
address of the interface (10-bit mode only). They
are not cleared when the interface is disabled
(PE=0).
Bit 0 = Reserved.
