ASAHI KASEI
b. Serial mode & AES3 mode (P/SN pin = “L”, AES3 bit = “1”, ASYNC bit = “0”)
Note 28. Channel status bit for RX can be monitored by CR191-0 bits and SDTO pin.
Note 29. Channel status bit for RX can be monitored by C pin, CR191-0 bits and SDTO pin.
Note 30. User bit for RX can be monitored by U pin and SDTO pin.
Note 31. Validity bit for RX can be monitored by VOUT pin, VRX bit and SDTO pin.
Note 32. C pin and CT191-0 bits are ORed internally.
Note 33. Channel status bit can select either CT191-0 bits or DAUX pin by the setting of CTX bit.
Note 34. VIN pin and VTX bit are ORed internally.
Note 35. When UDIT bit is “1”, the recovered U bits are used for DIT(DIR-DIT loop mode of U bit).
c. Parallel mode (P/SN pin = “H”)
