EP7309
High-Performance, Low-Power System on Chip
Internal Boot ROM
The internal 128 byte Boot ROM facilitates download of
saved code to the on-board SRAM/FLASH.
Packaging
The EP7309 is available in a 208-pin LQFP package, 256-
ball PBGA package or a 204-ball TFBGA package.
Pin Multiplexing
The following table shows the pin multiplexing of the
DAI, SSI2 and the CODEC. The selection between SSI2
and the CODEC is controlled by the state of the SERSEL
bit in SYSCON2. The choice between the SSI2, CODEC,
and the DAI is controlled by the DAISEL bit in SYSCON3
(see the EP7309 User
’
s Manual for more information).
The following table shows the pins that have been
multiplexed in the EP7309.
