■Function description

●HOST Interface

●Serial Peripheral Interface (SPI)

ML7344 has a SPI, which supports slave mode. Host MCU can read/write to the ML7344 registers and

on-chip FIFO using MCU clock. Single access and burst access are also supported.

[Single Access Mode Timing Chart]

In write operation, data will be stored into internal register at rising edge of clock which is capturing D0 data.

During write operation, if setting SCEN line to “H”, the data will not be stored into register. For more details of

SCEN negate timing, please refer to the “SPI interface characteristics”. Afetr the internal clock is stabilized,

data will be written into the register in syncrohonization with the internal clock.
