Of course, the waitstate values have a max of 31, not 15.

That's what the BCFG3 register is for (in your case.)  It sets the various access
modes (MW=0, RBLE=0), delays (DLCY=15) and wait states for READ (WST1=15)
and WRITE (WST2=15) using:

#define SET_BCFG(idcy, w1, rble, w2, mw) ( \
  (((mw) & 0x03) << 28) | (((w2) & 0x1f) << 11) | \
  (((rble) & 0x01) << 10) | (((w1) & 0x1f) << 5) | \
  ((idcy) & 0x0f))

so, BCFG3 = SETBCFG(15, 15, 0, 15, 0);

in your case.  This gives the slowest-possible 8-bit data/address bus for
the chip.  A0 is used as a "command/data" register switch, so, 0x83000000
is the command register (A0=0) and 0x83000001 is the data register (A0=1.)

Hi,

I would like to port my sed1335 driver to the lpc. I would like to use
it in memory mapped mode, so I connect data, rw, e, and cs lines. I
have an A0 pin on the lcd, which state is depends on that I want to
send data, or command.I plan to connect A0 to the address 0 of the
lpc, and than if i'm write to address 83000000 a0 will be 0, write to
83000001 A0 will be 1. (8bit bus) Will this work? :) I know I need to
set PINSEL2, BCFG3, but what about the delays. SED1335 is not a fast
device.

Any comments?

Thanks and Regards,
Andrew
