SPI FLASH Interface
The C5545 BoosterPack includes a 2MB Serial Flash (MX25R1635FM1IL0 from Macronix) which is
interfaced to the C5545 DSP as shown in
and the CC2650, which is selected through chip select 0 and 2, respectively.
The Hold signal (to pause the serial communication without deselecting the device) is disabled with a pull-
up resistor. Pull up/pull down options are provided for the write protect signal, which is disabled in the
default configuration.
