PWCTRO2 as Clock Output

Xilokar

I'm trying to ouput the 32k clock on PWCTRO2.

I set the GO2_FUNC bitfield of the GIO_FUNC register to 01, but it seems that the "muxing" of the PWCTRO2 pin is not done:

1. the 32k clock does not output.

2. I am still able to control PWCTRO2 state using the third bit of the GO_OUT register.

Am I missing a configuration step ?

regards.

Xilokar,

This is a known documentation issue. Actually the GO_FUNC bit (01/10/11) enable the output to come out on the PWCTRIO2 pin.

We will be updaing the Userguide with the fix.

regards,

miguel

In the latest PRTCSS documentation from august 2011, this is not yet fixed...

Can you confirm the 32kHz clock can be output on PWCTRIO2 pin following the exact procedure described in the current PRTCSS documentation?*

Are there any other such undocumented issues in the PRTCSS?

Thanks.

Just an update for anybody who runs across this:

This is a known issue and we just confirmed that the 32Khz clock does indeed come out on the PWCTRIO2 pin instead of the PWCTRO2 pin. So if you are designing a board, make sure you wire up anything needing a 32Khz clock to PWCTRIO2 instead of PWCTRO2.
