F28069 modules that are not reset by internal reset (by MCLKRS)

Piotr Romaniuk

Hi,

having the reset that occurs when clock fails is a great functionality.
Unfortunatelly, internal reset caused by missing clock detection logic (MCLKRS) is not so full as external reset by XRS input.

What are differences between these two types of reset?

At least I saw that INTOSC1OFF is not changed by internal reset.

Piotr,

MCLKRSn is similar to a debugger reset (SYSRSn), it will reset CPU, peripheral, I/O configuration. But, it doesn't affect JTAG (or) pull XRSn low.

Hi Manoj,

may I ask you for enumeration what exactly is not reset by MCLKRS?
(I run the cpu standalone, without JTAG)

For example, one of such features is INTOSC1OFF.
