I saw the code below in the I2C example code. Is there an updated errata that mentions this issue and which silicon revisions are/were effected? The errata I found only talked about an ADC issue for revs A and B. The code uses the 'fixed' version, but when was it fixed?

void I2CSlaveInit( void ) 
{
  /* SSP and I2C reset are overlapped, [B]a known bug[/B], 
  for now, both SSP and I2C use bit 0 for reset enable. 
  Once the problem is fixed, change to "#if 1". */
#if 1
  LPC_SYSCON->PRESETCTRL |= (0x1<<1);
#else
  LPC_SYSCON->PRESETCTRL |= (0x1<<0);
#endif

Did you find an answer to this? I wanted to ask the same question.

[FONT=&quot]This was a comment from the early silicon validation. It is fixed in the released silicon.

The code sh[/FONT][FONT=&quot]ould read as follows:
[/FONT][FONT=&quot]LPC_SYSCON->PRESETCTRL |= (0x1<<1);
