TMS570LC4357: External Clock Monitor (ECLK1)

Part Number: TMS570LC4357

Hello

We have questions about ECLK functionality.

Is it possible to deactivate the External Clock Monitor (ECLK1) fucntionality ?

- via the GIO mode (ECPCLKFUN bit of SYSPC1 register at 0x0) ?

- or via the Clock test mode (CLK_TEST_EN bit of CLKTEST register at 0xA (default value)) ?

Best regards,

Christopher

Hello,
Setting CLK_TEST_EN bits to number other thatn 5h, disables clock test mode. Even ECLK1 pin is set to functional (ECPCLKFUN bit is 1) you will not see any clock on it.
If you set CLK_TEST_EN bits to 5h and ECLK1 pin as functional (ECPCLKFUN bit is 1) then you will see clock on it.
If you set CLK_TEST_EN bits to 5h and ECLK1 pin as GIO (ECPCLKFUN bit is 0), you will not see any clock on ECLK1 pin.

Best regards,
Miro

Thanks for your answer.
and Setting CLK_TEST_EN bits to number other thatn 5h, also disable the GIO functionality of ECLK pin ?

Hello,
This bits only enables/disables clock going to ECLK pin. For setting GIO/Functional mode, bit ECPCLKFUN is used.
