MCXE24x WDOG clocks configuration not defined in reference manual

[nd_psi]

I want to configure the WDOG clock source in the WDOG_CS register. The description of the field CLK (bit 9-8) mentions too look at the ""chip-specific information" to determine the value. Looking in the ""chip-specific information"  i only see a list with clock source but not with the bit value. What are the corresponding values with the clock sources?

Hello,

In Reference Manual page 5292 Table 25-9 contains an image that could help you with the bit configuration for selecting clock sources for WDOG_CS [CLK],

If you have any further questions, please let me know.

Hello @luis_maravilla ,

Thank you for your reply.

The reference manual on your website for the MCX-E24x only contains 1949 pages.

Kind regards,
Niels

Hello Niels,

I apologize it was a typo mistake; I meant to write page 529 Table 25-9.

Hello @luis_maravilla ,

I found it thanks for your help,

I notice a contradiction in this figure: SOSC is connected to “internal clk” while SOSC is the external crystal. SIRC_CLK is connected to “external clk” while this is the slow internal clock. Which label is correct (SOSC or internal clk)?

Kind regards

Niels

The WDOG_CS module according to the documentation specifies

CLK 00b – Bus clk

CLK 01b – LPO_CLK

CLK 10b – Internal_CLK

CLK 11b – external_CLK

But at the system level, the clocks for the module are routed as follows:

The internal_clk is routed to SOSC_CLK source; The external_clk is routed to SIRC_CLK source

Therefore, both labels are correct, I apologize for the labeling confusion.
