Digital Echo/Surround Processor IC

PT2396

MCU MODE

The MCU Mode is activated when the EASY/(/MCU) Pin is in Low State. The delay time is set by the

serial data from the MCU. Please refer to the timing diagram below:

where: Delay time = DL1 ~ DL4

ID code = ID1 ~ ID4

The DIN Signal is shifted in the falling edge of the CLK Signal when the ID Code Bits values are verified

as follows:

ID1 and ID3 = Low

ID2 = High

ID4 = IDS Pin

then, the last ten data bits are latched at the rising edge of the REQ Signal.

When 2 pieces of PT2396 are used, Pin 7 determines which PT2396 is in control. Pin 7 may be pulled

High or Low. Please refer to below:
