EMA[18:0]: Address Bus
Address of the external SRAM. Used to select a data entry in the external SRAM.
EM_WE: Write Enable
Write enable signal for the external SRAM. When EM_WE pin and EM_CS pin are both low, data can
be written to the external SRAM.
EM_OE: Output Enable
Output enable signal for the external SRAM. When EM_OE pin and EM_CS pin are both low, data can
be read from the external SRAM.
EM_CS: Chip Select
Chip enable signal for the external SRAM.
TCK: JTAG Test Clock
This pin is the input clock for JTAG.
TMS: JTAG Test Mode Select
This pin has an internal pull-up resistor.
TDI: JTAG Test Data Input
This pin is used to load instructions and data into the test logic and has an internal pull-up resistor.
TDO: JTAG Test Data Output
This is normally high impedance and is used to read all the serial configuration and test data from the
test logic.
TRST: JTAG Test Port Reset
This pin has an internal pull-up resistor.
