extermal memory timing

try chris' external memory timing

XintfRegs.XTIMING6.all = 202281;

motor does not turn

change back

from the data sheet, here is an example of valid timings when not sampling XREADY

0000 0000 0100 0011 1001 0000 0010 0000
or
00000000010000111001000000100000
or
4427808

(31-24) 0000 0000 - reserved
(23) 0 - reserved
(22) 1 - X2TIMING
(21-18) 00 00 - reserved
(17-16) 11 - XSIZE
(15) 1 - READYMODE
(14) 0 - USEREADY
(13-12) 01 - XRDLEAD
(11-9) 000 - XRDACTIVE
(8) 0 - XRDTRIAL
(7) 0- XRDTRIAL
(6-5) 01 - XWRLEAD
(4-2) 000 - XWRACTIVE
(1-0) 00- XWRTRIAL

motor makes a lot of ugly noise but does not run

I must need to use XREADY

I cannot find the data sheet for the external memory that I need to determine the wait states as the internet is playing up.

I will work on the current sensor problems instead.
