CFG->GCR =0x00; //----work, typo error at the datasheet?

Hi MCU Lüfter

CFG->GCR =0x00;

using that value work, as I can use the port like toggle. but im not sure if the AL bit will be affected and also im still having problem using beep.

I think ill need some official statement on the SWIM bit.

Also one of my unit SWIM disable, as like could not use it anymore. Reference manual says, at start up SWIM will be ON, therefore I can still use SWIM with POR reset.

later ill try reading SWIM bit in a normal condition.......

Hi leo,

How are you checking this ?

Hi.

I got my Buzzer working, and GPIO on SWIM pin, with and without changing SW bit

in that CFG->GCR =0x00; and CFG->GCR =0x01; will work., but observe on scope, CFG->GCR =0x01; take long to have a stable output, compared to CFG->GCR =0x00;

but using as GPIO, both work.

Hi leo,

Are you making these tests in standalone mode or in debug mode ?

Hi MCU Lüfter

on standalone mode, I mean on my custom PCB. Oh I never even tried debug mode.

also im using RST pin sa GPIO, maybe it would have some effect.
