Ladies and Gentlemen,
It seems I have found more failures in the LPC553x Reference Manual, Rev. 3, 07/2023.
Let me say, it is extreme difficult to properly program such a microcontroller, when it is so bad documented.
Here are my findings today:
Chapter 47.1.2, Figure 265, Page 1984,
Chapter 47.1.4, Table 389, Page 1984:
ADC0IN2A in Table389 connected to OPAMP2OUT and muxed by ADC0IN2B and ADC1IN0A. On Figure265 it is connected to OPAMP2_OUT, ADC0IN7B, ADC1IN0A and ADC1IN7B.
ADC0IN5A on Figure265, the grey line doesn't connect to VREF_OUT.
ADC0IN6A in Table389 connected to OPAMP0_VREFH_ADC. What is this signal? ON Figure265, it is connected to ADC1IN6A, PIO1_9 and OPAMP0_OUT.
ADC0IN7A in Table389 connected to OPAMP2_VREFH_ADC. What is this signal? On Figure265, this input is not connected.
ADC0IN0B in Table389 connected to OPAMP1_OUT. On Figure265 it is also connected to ADC0IN6B and ADC1IN6B
ADC0IN1B is not listed in Table389, but on Figure265 it is connected to Pin ADC0IN1B. Which Pin is this? Cannot find it in the datasheet.
ADC0IN2B in Table389 connected to OPAMP2_OUT. In Figure265 it is not connected.
ADC0IN5B in Table389 is muxed with ADC1IN5B. On Figure265 there's no sign of this mux-ing. Where is ADC0IN5B connected?
ADC0IN6B in Table389 connected to OPAMP1_VREFH_ADC. What is this signal? On Figure265 it is connected to OPAMP1_OUT and also to ADC0IN6B.
ADC0IN7B in Table389 connected to OPAMP2_VREFH_ADC. What is this signal? On Figure265 it is connected to OPAMP2_OUT and ADC0IN2A and ADC1IN0A and ADC1IN7B.
ADC1IN0A in Table389 muxed with ADC0IN2A and ADC0IN2B. On Figure265 it is muxed with ADC1IN7B, ADC0IN2A and ADC0IN7B.
ADC1IN5A in Table389 connected to VREF_OUT and muxed with ADC0IN5A. On Figure265, ADC0IN5A's grey line doesn't connect.
ADC1IN0B in Table389 is connected to PIO1_0. On Figure265 it is connected to P1_10. The datasheet say PIO1_0, too.
ADC1IN1B in Table389 is told as dedicated. On Figure265 it looks like connected to a pin, but there's no such pin called ADC1IN1B.
ADC1IN4B in Table389 connected to DAC2_OUT. On Figure265 it is not connected.
ADC1IN5B in Table389 connected to VREFN. On Figure265 it looks like a pin connection but there's no such pin.
ADC1IN6B in Table389 connected to OPAMP1_VREFH_ADC. What is this signal? On Figure265 it is connected to OPAMP1_OUT, ADC0IN0B and ADC0IN6B.
ADC1IN7B in Table389 connected to OPAMP2_VREFH_ADC. What is this signal? On Figure265 it is connected to OPAMP2_OUT, ADC1IN0A, ADC0IN2A and ADC0IN7B.
On Figure 265, ADC0 and ADC1 A and B side, input 10, 26 and 27 are hard to read.
