(8) Special use
1) External connection mode
Normally, OPCL is used at "L" (internal connection mode), but when OPCL is set to "H", the ADC output and
DAC1/DAC2 inputs can be used independently form DSP. (External connection mode)
OPCL = "H": External connection mode
The following shows the input/output interface in external connection mode:
• SDINA for MSB-first 24-bit input (including I²S compatibility)
• SDOUTA for MSB-first 20-bit output (including I²S compatibility)
• SDOUTD1 and SDOUTD2 for MSB-first 24-bit outputs (including I²S compatibility)
• SDIND1 and SDIND2 for MSB-first 20-bit inputs (including I²S compatibility)
Conversion between the input/output standard format and I²S is interlocked with the control register C0, similar to the
case for internal connection mode.
