TAS2560: Need TAS2560 Example CFG to Send IRQ# and Error Flags on Clock Error

Wayne Chen (Audio AE)

Part Number: TAS2560

Hi Sirs,

Would you please provide an example CFG to program the TAS2560 to send an IRQ# (either active high or low is fine) and assert error flags on CLK error of I2S ASI-1?
Should we program the registers of 0x21, 0x22, 0x23, 0x4f and 0x50?

Thank you and Best regards,

Hi Wayne,

You're correct on the required registers to configure:

You should set bit 1 from register 0x21 to enable clock error detection block 1
Register 0x23 can be left with default values
You can use bits 7-6 from register 0x24 to select the kind of notification on IRQ pin you want to get, 1 short pulse, repetitive pulses or steady signal
You should set the mask for the desired interrupts to trigger IRQ pin on register 0x25, in this case you want to set bit 2

Thank you for your advise, Ivan. It works on the TAS2560 EVM:

w 98 00 00
w 98 7f 00
w 98 21 03
w 98 25 ff

Polling 0x26:

r 98 26 01 -> returned 0x02 = normal operation
r 98 26 01 -> returned 0x22 = CLK error

Thank you and Best regards,
