• Description: Recording/playback Equalizer Amplifier
• Manufacturer: Sony Electronics

2. 11-bit serial data interface
• The DATA signal is taken in at the rising edge of the CLK signal.
• The DATA signal is taken in to the internal shift register when the LATCH signal is low.
• The internal shift register data is latched and output in parallel at the rising edge of the LATCH signal.
• The CLK signal of 11th bit should fall after the LATCH signal rises.
• Reset is done when the XRESET pin is low. (asynchronous method)
(Outputs (Pins 13 to 22) hold the previous value while the LATCH signal is low.)
(Internal shift register data is loaded while the LATCH signal is high.)
Outputs (Pins 13 to 22) are all high (open) during reset.
