Looking at the CYT4BB clocking diagrams, the only > 1MHz clock option for the watchdogs (WDT, MCWDT) appears to be the ECO.

This is a problem for me, because I am using an oscillator with EXTCLK. The EXTCLK pin used however is 21.2, which is shared with the ECO.

Question: Is it supported to use ECO with an external (LVCMOS, 3.3V) oscillator rather than a crystal?

P21.3 is unconnected, so no concerns about load levels etc on that pin.

Hello,

The ECO circuit is expected to work with crystal, so external oscillator can not be used with the same. 

Thanks.
