ADC Channel Select Register (ADxxSEL) : Number of bits

Adrien Burghgraeve

Hi,

in the documentation SPNU499 of the TMS570, there are several mistakes :

- in figure 18-47 : EV SEL is 24-bit long, but 16-bit long in table 18-37 (in ADEVSEL)
- same problem for ADG1SEL, ADG2SEL...

What is the correct length of this fields ?

Andrien,

Each bit in those registers represent one A/D channel. An A/D module can support up to 24 channels. If there are 16 channels on the device, only 16 bits are valid. I will pass this information to the TRM owner.

Thanks and regards,

Zhaohong
