C Interface
A standard I
2
C interface is used to communicate between the PD64012 and the host controller.
The PD64012’s I
2
C interface is designed to support the following features:
SLAVE mode only
Normal-mode and Fast-mode data rate (0 to 400 kb/s)
7-bit addressing - the 7-bit addressing (128 addresses) uses the following address code:
First MSB = “0” (forced by internal logic)
4 MSB address bits are set via the I2C_INI pin, according to the following table
“
mm
” bits are set through the ASIC_INI pin (Enhanced mode = “00”; Automatic mode Master
=”00”; Automatic mode Slave = “01”, “10”, “11”)
“
xxx
” - 3 LSB are ignored.
