Hi all,

While working on the LPC800 chip I have discovered an error in the User Manual.

'Table 203. Register overview: SPI (base address 0x4005 8000 (SPI0) and 0x4008 C000
(SPI1))' Page 236 of UM10601 v1.6

The address for SPI1 should infact be 0x4005 C000

This while a small issue did indeed have me wondering when I was trying to debug an issue with SPI1.

Otherwise I love the chip it is great.

In the data sheet it says:

Quote:
Remark: SPI0 is available on all LPC800 parts. SPI1 is available on parts
LPC812M101JDH16 and LPC812M101JDH20 only.

Does that really mean that there is no SPI1 on LPC812M101JD20 ?
Even though the pinout is the same as the LPC812M101JDH20?

It does indeed mean that the SOIC20 only has 1 SPI interface where as the TSOP20 has 2 SPI interfaces. I'm speaking for first had experience here, you have to be careful which chip you select.

I felt when I figured out what was going on and investigated the number is SPI blocks. It is correctly documented and the problem is clearly mine.
