ADE5166/ADE5169/ADE5566/ADE5569
I 2 C-COMPATIBLE INTERFACE
The ADE5166/ADE5169/ADE5566/ADE5569 support a fully
licensed I 2 C interface. The I 2 C interface is implemented as a full
Data Sheet
The bit rate is defined in the I2CMOD SFR (Address 0xE8)
as follows:
hardware master.
SDATA (P0.4/MOSI/SDATA) is the data I/O pin, and SCLK
f SCLK =
f CORE
16 × 2 I 2 CR [ 1 : 0 ]
(P0.6/SCLK/T0) is the serial clock. These two pins are shared with
the MOSI and SCLK pins of the on-chip SPI interface. Therefore,
the user can enable only one interface at a time on these pins. The
SCPS bit in the configuration SFR (CFG, Address 0xAF[5]) selects
which peripheral is active.
The two pins used for data transfer, SDATA and SCLK, are
configured in a wire-AND format that allows arbitration in a
SLAVE ADDRESSES
The I 2 C slave address SFR (I2CADR, Address 0xE9) contains
the slave device ID. The LSB of this register contains a read/write
request. A write to this SFR starts the I 2 C communication.
I 2 C REGISTERS
The I 2 C peripheral interface consists of five SFRs.
multimaster system.
?
I2CMOD
The transfer sequence of an I C system consists of a master device
2
initiating a transfer by generating a start condition while the bus
is idle. The master transmits the address of the slave device and
the direction of the data transfer in the initial address transfer. If
the slave acknowledges, the data transfer is initiated. This continues
until the master issues a stop condition and the bus becomes idle.
SERIAL CLOCK GENERATION
The I 2 C master in the system generates the serial clock for a
transfer. The master channel can be configured to operate in
fast mode (256 kHz) or in standard mode (32 kHz).
Table 156. I 2 C SFR List
? SPI2CSTAT
? I2CADR
? SPI2CTx
? SPI2CRx
Because the SPI and I 2 C serial interfaces share the same pins,
they also share the same SFRs, such as the SPI2CTx and SPI2CRx
SFRs. In addition, the I2CMOD, I2CADR, and SPI2CSTAT SFRs
are shared with the SPIMOD1, SPIMOD2, and SPISTAT SFRs,
respectively.

Description
Address of the I 2 C slave being addressed. Writing to this register starts the I 2 C transmission (read or write).
Command bit for read or write. When this bit is set to Logic 1, a read command is transmitted on the
I 2 C bus. Data from the slave in the SPI2CRx SFR (Address 0x9B) is expected after a command byte.
When this bit is set to Logic 0, a write command is transmitted on the I 2 C bus. Data to the slave is
expected in the SPI2CTx SFR.
