Write cycle
The following chronogram describes the write cycle :
All the Cpu signals are re-synchronised with the Ck50 (APC esclk signal clock) clock signal.
The Rwn, Data and Address signals are only valid when the Csn signal is active low. The Csn, Rwn, Data and Address signals
should stay stable until the Rdyn signal goes low.
When the Rdyn signal goes low, it means the data has been written in the FPGA.
The Rdyn signal stays low until the Csn signal goes high again.
The Rdyn signal is in thee-state by default.
1.8
Read cycle
The following chronogram describes the read cycle :
All the Cpu signals are re-synchronised with the Ck50 (APC esclk signal clock) clock signal.
The Rwn, Data and Address signals are only valid when the Csn signal is active low. The Csn, Rwn, Data and Address signals
should stay stable until the Rdyn signal goes low.
When the Rdyn signal goes low, it means the data can be sampled by the CPU.
The Rdyn signal stays low and the data stay valid until the Csn signal goes high again.
The Rdyn signal is in thee-state by default.

FPGA Timing
The ORCA 3T30-6-S208 respect the following timing :
-
-
-
-
FPGA Clock_to_Out = 8 ns (refer to external clock).
FPGA Input setup time = 8 ns (refer to external clock).
FPGA Hold time = 1 ns (refer to external clock).
External Frequency = 50MHz (20ns period).
