CX29503 Data Sheet
8.3.2.9
Five transmit Sa-Byte buffers (TSA4–TSA8) are used to insert Sa-bits in TS0. The entire group of 40 bits is
sampled every 16 frames, coincident with the TMF interrupt boundary [addr: 008]. Bit 0 from each TSA
register is then inserted during Frame 1, Bit 1 during Frame 3, Bit 2 during Frame 5 and so on. This gives the
processor up to 2 ms after the TMF interrupt to write new Sa-Byte buffer values. Transmit Sa-bits maintain a
fixed relationship to the transmit CRC multiframe.
