Veronica should be able to change the semaphore too.

686 04/13/2018 10:11 PM markw

Disable err_i, with that high cpu freezes on rdy dropped. Re-reading example it was held low there.

685 04/13/2018 09:39 PM markw

Latest 65816 changes from Robs github

684 04/13/2018 09:14 PM markw

Board has CE2, not CE_N connected to this pin. So need to use 1 to enable sram.

683 04/13/2018 09:13 PM markw

Back off by 2 cycles, make it more reliable (was missing some eclairexl writes)

453 04/28/2016 10:35 PM markw

Plugged in the sram model to check timings

452 04/28/2016 10:34 PM markw

Need to review further, but these changes seem to bring the 65816 core to life somewhat

451 04/23/2016 03:28 PM markw

Added testbenches. Do not respond to bus cycles that do not target the cart

450 04/22/2016 11:11 PM markw

sram model for tb

449 04/22/2016 10:28 PM markw

Moved memory timing bridge inside slave_timing, its an internal detail really
