Register Name:
RSa8
Register Description:
Receive Sa8 Bits (E1 Mode Only)
Register Address:
base address + 0x1B4
Bit # 7 6 5 4 3 2 1 0
Name RSa8F15 RSa8F13 RSa8F11 RSa8F9 RSa8F7 RSa8F5 RSa8F3 RSa8F1
Default 0 0 0 0 0 0 0 0
The Sa8 bits received in each multiframe are saved in internal registers and latched into this register at the start of
the next CRC-4 multiframe. The CRC-4 multiframe boundary is indicated by the RCMF status bit in RLS2-E1. See
Section 10.11.5.2.
Bit 7: Sa
8 Bit of Frame 15 (RSa8F15).
Bit 6: Sa8 Bit of Frame 13 (RSa8F13).
Bit 5: Sa8 Bit of Frame 11 (RSa8F11).
Bit 4: Sa8 Bit of Frame 9 (RSa8F9).
Bit 3: Sa8 Bit of Frame 7 (RSa8F7).
Bit 2: Sa8 Bit of Frame 5 (RSa8F5).
Bit 1: Sa8 Bit of Frame 3 (RSa8F3).
Bit 0: Sa8 Bit of Frame 1 (RSa8F1).
Register Name:
SaBITS
Register Description:
Receive Sa Bits (E1 Mode Only)
Register Address:
base address + 0x1B8

Name - - - Sa4 Sa5 Sa6` Sa7 Sa8
Default 0 0 0 0 0 0 0 0
This register indicates the last received Sa bits. This can be used to determine which Sa bits have changed. The
user can program which Sa bit positions should be monitored via the RSAIMR regi
ster, and when a change is
detected through an interrupt in
4RLS7-E1:SaXCD, the user can determine which bit has changed by reading this
register and comparing it with previous known values. See section 10.11.5.3.
Bit 4: L
ast Received Sa4 Bit.
Bit 3: Last Received Sa5 Bit.
Bit 2: Last Received Sa6 Bit.
Bit 1: Last Received Sa7 Bit.
Bit 0: Last Received Sa8 Bit.
