ADE7763 Interrupts ZXTO and SAG - different behavior between two devices


I have two ADE7763 connected via SPI to MCU (ATTINY416). ZXTO Interrupt work and SAG Interrupt don't work at the first device. ZXTO Interrupt don't work and SAG Interrupt work at the second device. Why?

Devices Registers Setup:
SAGLVL = 0x12
MODE = 0x0004
IRQEN = 0x1010 for ZXTO or 0x0012 for SAG detection

-SS/ and IRQ/ are wired individually to MCU
-ZX Interrupt work with both devices.

Best Regards
