Dear all,
my colleague has faced an issue during setting of ADC module - he has identified a contradiction of TRM (SPNU563, May 2014) chapter with the real behavior.
- The device: TMP570LC4357AZWT on HDK
- The intended functionality: to use all the ADC inputs for external signal measurement, the inner temperature sensors are disabled.
The TRM chapter 6.5.13 Temperature Sensor Selection states:
Before the temperature sensors can be used, they must be enabled. By default, they are disabled with PINMMR174[24] = 1. To enable the temperature sensors, PINMMR174[24] must be cleared to 0.
Contradictory to this statement, the properly working (ADC1_31 does measure the external voltage) code looks like:
pinMuxReg->PINMUX[174] &= (U32) (~0x01000000); //Enable ACH1(31) measurement
The conclusion by my colleague is:
- PINMUX[173] configures what is measured
- PINMUX[174] enables the measurement
Please, may you check this description and behavior?
Many thanks in advance,
Best regards, Jiri
