BIT NAME AND DESCRIPTION
7
Line Interface Reset.
Setting this bit from a zero to a one will initiate
an internal reset that affects the clock recovery state machine and jitter
attenuator. Normally this bit is only toggled on power–up. Must be
cleared and set again for a subsequent reset.
6
Receive Elastic Store Align.
Setting this bit from a zero to a one may
force the receive elastic store’s write/read pointers to a minim separation
of half a frame. No action will be taken if the pointer separation is
already greater or equal to half a frame. If pointer separation is less then
half a frame, the command will be executed and data will be disrupted.
Should be toggled after SYSCLK has been applied and is stable. Must
be cleared and set again for a subsequent align. See Section 16 for
details.
5
Receive Elastic Store Reset.
Setting this bit from a zero to a one will
force the receive elastic store to a depth of one frame. Receive data is
lost during the reset. Should be toggled after SYSCLK has been applied
and is stable. Must be cleared and set again for a subsequent reset. See
Section 16 for details.
4
Receive Channel Monitor Bit 4.
MSB of a channel decode that
determines which receive channel data will appear in the RDS0M
register. See Section 9 for details.
3
Receive Channel Monitor Bit 3.
2
Receive Channel Monitor Bit 2.
1
Receive Channel Monitor Bit 1.
0
Receive Channel Monitor Bit 0.
LSB of the channel decode.
