ATM/HDLC/SDL Counter 1
Channel [0—3]. Keeps a count of
conditions detected by the data framer in the
particular channel. This register can
represent only one of the following based
upon the channel’s payload type:
I
I
I
This value is updated upon assertion of
PMRST, and the real-time counter value is
reset to zero.
From IETF RFC 1622, invalid sequences are
the following:
1. Frames which are too short (less than 4
data bytes). See register PM_FC2_0
(addresses 0x1108—0x110F).
2. Frames which end with a control escape
octet followed immediately by a coding flag
sequence (0x7D7E).
3. Frames in which octet framing is violated
by transmitting a 0 stop bit where a 1 bit is
expected.
Reserved. These bits must be written to
their reset default value (0x0).
[11:4] is the MSByte of PM_FC1_0.
[7:0] is the LSByte of PM_FC1_0.
Reserved. These bits must be written to
their reset default value (0x0).
[11:4] is the MSByte PM_FC1_1.
[7:0] is the LSByte of PM_FC1_1.
Reserved. These bits must be written to
their reset default value (0x0).
[11:4] is the MSByte of PM_FC1_2.
[7:0] is the LSByte of PM_FC1_2.
Reserved. These bits must be written to
their reset default value (0x0).
[11:4] is the MSByte of PM_FC1_3.
[7:0] is the LSByte of PM_FC1_3.
