I/O
— Ground terminal for core.
I Latch input terminal for microcomputer serial communication. Latches address and data at falling this signal.
Shift clock input terminal for microcomputer serial communication. Reads and shifts serial input data at the
I rise-up of the clock that is input into this terminal. When reading out, read data changes at falling of clock that
inputs into this terminal.
Data input terminal for microcomputer serial communication. Inputs data and address with serial from
I
microcomputer.
— Power terminal for core. Supply +2.5 V.
O Date output terminal for microcomputer serial communication. Hi-Z excluding output.
O Output ready flag for microcomputer serial communication. When completing, outputs "L". Open drain.
Output enable terminal for microcomputer serial communication. When using tri-state buffer externally, activates
O
by this terminal. When outputs "MSDATO", "L" is shown.
Reset terminal. Resets entire IC on "L". Clock that is output from EXCK01, EXCK02 and LRCK of output
I
terminal, doesn't stop in resetting.
I Soft mute terminal. Soft-mutes audio output with "H" and releases it with "L".
I Master clock input terminal. Inputs clock with 768 Fs (33.8688 MHz).
— Ground terminal for input and output.
O External output clock terminal 1. Upon setting, outputs 768 Fs, 512 Fs, 256 Fs and 128Fs.
O External output clock terminal 2. Upon setting, outputs 768 Fs, 512 Fs, 256 Fs and 128Fs.
O 1Fs(44.1kHz) clock output terminal.
O Frame signal output terminal.
