Hi. In the ADSP-21262 datasheet (Rev B) is it stated that the TCK line (used for JTAG port) "must be asserted (pulsed low) after power-up or held low for proper operation of the ADSP-21262". However, in the ADSP-21262 EZ-KIT LITE schematic diagram it is pulled- up to mantain a high when you just run the DSP without JTAG intervention. Of course the TRST* must be held down after power-up bu...

Hello, I've implemented filtering on the ADSP-21364 with a sampling rate of 48kHz. I use both analog and SPDIF interfaces. And in each case, if I enter, for example, coefficients of a low-pass filter with a cutoff frequency of 500Hz, the signal is filtered by a low-pass filter with a cutoff frequency of 1000Hz. So everything seems to be as the processor would read and write samples at ...
