Figure 14: Connecting external SPI Memory to AMY-6M
Only use Serial FLASH types listed in Table 15.
It is not recommended to use Serial Flash at SPI for new designs.
The SPI signals at AMY-6M are at VDD_IO voltage levels. VDD_IO must be supplied with same voltage as
external serial FLASH.
2.3.4.2
Detection of SPI serial FLASH
The AMY-6M only detects the serial FLASH if all the SPI pins (CLK, SS_N, MOSI and MISO) are high. This is the
case if only the serial FLASH is connected to the SPI interface pins.

SPI communication (connecting to an SPI host/master)
Figure 16 shows how to connect an AMY-6M to a host/master. The signal on the pins must meet the conditions
specified in the Data Sheet.
