3.0 Registers
3.11 Receive Sa-Byte Buffers
3.11 Receive Sa-Byte Buffers
Five receive Sa-Byte buffers [RSA4–RSA8] are double-buffered. All five registers are updated with the Sa-bits
received in TS0 of odd frames at each receive multiframe interrupt [RMF; addr 008]. Bit 0 of all RSA registers
contains data from frame 1, Bit 1 contains data from frame 3, Bit 2 contains data from frame 5, etc. This gives
the processor a full 2 ms after RMF interrupt to read any Sa-Byte buffer before the buffer content changes.
Processor should ignore RSA buffer contents at all times during T1 mode and also when receiver reports loss of
FAS alignment [FRED=1; addr 049] in E1 mode.
