Default
Bit 9: Receive Voice FIFO Reset (RVFRST)
powered down, and all incoming data is discarded.
Bit 8: Receive Voice Clock Invert (RVCLKI)
Bits 3-7: Receive Voice Octets Per Frame (RVOPF[4:0]). Controls the number of octets that are used for voice
traffic per frame. Note: Max. number of octets allowed to be used for voice is 16.
Bit 2: RSYNC Control (RSYNCC). This setting is necessary only if voice ports are enabled. RVSYNC MUST be a
frame sync.
Bit 1: Port Configuration (PC). Used to divide down multiframe sync to frame sync.
Bit 0: Receive Port Enable (RPE)
Rev: 063008

0 = The Receive Voice FIFO resumes normal operations
1 = Receive Voice FIFO Reset. The FIFO is emptied, any transfer in progress is halted, the FIFO circuit is
0 = RVCLK is not inverted
1 = RVCLK is inverted
00001 = 1
00010 = 1
0 = RSYNC is a frame sync. Voice bytes inserted into Voice FIFO after every RSYNC.
1 = RSYNC is a multiframe sync. Voice bytes inserted into Voice FIFO based on PC register bit.
0 = Port is configured for T1.
1 = Port is configured for E1.
0 = Port is Disabled
1 = Port is Enabled
