I2C bus 7-bit address
I2C1_CH1 0x6A
0x08
I2C1_CH2 0x40
I2C1_CH3 0x4C
0x51
I2C1_CH4 I2C address is
defined by the
plugged-in PCIe card
I2C1_CH5 I2C address is
defined by the
plugged-in PCIe/
SATA card
I2C1_CH6 I2C address is
defined by the
plugged-in mikro-
click module
I2C1_CH7 I2C address is
defined by the
plugged-in mikro-
click module
A 7-bit address does not include the read/write (R/W) bit as an
address member, though some datasheets might do so. For
consistency, all I2C addresses above are of 7 bits only.

2.13 XSPI interface

The LS1028ARDB octal serial peripheral interface (XSPI) supports two onboard XSPI
serial flash memories (NOR flash and NAND flash) for boot image and one QSPI
emulator for offboard QSPI emulation. The XSPI chip-select signals from the processor
are driven to the XSPI memories or to the QSPI emulator through two high-speed
multiplexers.
