s12zvl pin PL0/hvi divider ration

[charudattaingal]

Hi All,

I want to set divider ratio of  s12zvl macro pin no 2  PL0/Hvi to 1:9.

I tried by setting PIRL_PIRL0 bits but not getting 1:9 ratio.

Requesting assistance.

Have a nice day !

Thanks & Regards,

Charudatta

Hi Charudatta,

I am afraid that this is just misunderstanding.

Ratio 1:9 could be set for VSUP measurement.

HVI input ratio could be set as RatioL_HVI (=1:2) or RatioH_HVI (=1:6) by PIRL_PIRL0 bit.

Additionally you have to also route divider to ADC by PTAD_PTAENL=1.

For example: PTAL = 0x08; //HVI0 connected to ADC.

Optionally you could also bypass voltage divider and connect HVI input directly to ADC by PTAD_PTADIRL=1 (valid only when PTAD_PTAENL=1).

For example: PTAL = 0x18; //HVI0 connected to ADC, bypass divider.

I hope it helps you.

Have a great day,
RadekS
