Lpc2000

Hi All

While waiting for my LPC2106 board to arrive (Thanks for all the help on my
former topic around the LPC2106 processor!!!) I'm now very interessted in
the LPC2214 (because of the ext. mem interface, more IO and pheripals)

How ever some questions came to me last night while drawing the LPC2214 into
protel

1. The BSLx pins, all memory IC's i've used had a software bank select are
these pins used to hardware select banks on large memory devices, if yes
could you recommend any compatible ?

2. I would like to use all 8 pins of the ADC but these are mapped to BSL
pins 2 / 3 This means (if im correct) that
any memory i connect cant use more than BANK 0 and 1 because i want BANK2+3
used for the ADC

3.
I had this in mind:
I saw that BOOT could be set so that CS0 would select a bootable flash
insted of the internal (very smart)
On default the device boots from the external flash, (CS0) it is then
possible to "invoke" a special bootload where the
BOOT pins are shifted so that the LPC boots from internal flash where a
"bootloader" programs the external flash, maybe from GPRS,UART or some other
source and then when finished it sets the BOOT pins for external flash and
resets it self
(all this should be done with an external chip im thinking ATmega8515 or
something similar)

4.
From past experience with ARM that I was able to specify the bandwidth of
the databus/address bus
I am probertly not going to use any external devices with more than 16 data
and 20 address pins.
(unless you guys know some fancy part which is a must have :) so is it
possible to specify (for instance)

5.
I have a device on CS0, it has 16 data and 20 address pins, this is the
largest part in my design
can I then allocate the rest of the data pins as GPIO and the rest of the
address pins as general purpose outputs ?

6.
Can I use all the TRACExxx, PIPExxxx pins as general purpose pins (ofcause
respecting their fixed I/O setting) ?

7.
Wanting to add a regular JTAG (not the fancy one with a million pins) for
programming the internal flash
can I use Leon Heller's schematic as a reference
(Files->Hardware->JTAG->Jtag.pdf) ??

8.
Why in god's name did philips select the DCD pin which is an input on the
modem interface for sampling the bootloader
I think this is the worst pin possible to select, it renders this pin on the
modem interface useless unless i want to add a bunch of extra components,
Shame on you philips, there are other pins, use them insted !

9.
Can any one suggest some compatible flash or ram devices for the LPC2214 ???

Thanks for reading !
