ATM Idle Cell Register Channel [0—3].
This 32-bit register will store the expected
header value for idle cells. If the ATM framer
sees a header for an ATM packet which
matches this register at the bit positions
designated by the ATM idle cell match mask,
the packet will be treated as an idle cell.
[31:24] is the MSByte of ATM_IDC_0.
[7:0] is the LSByte of ATM_IDC_0.
[31:24] is the MSByte of ATM_IDC_1.
[7:0] is the LSByte of ATM_IDC_1.
[31:24] is the MSByte of ATM_IDC_2.
[7:0] is the LSByte of ATM_IDC_2.
[31:24] is the MSByte of ATM_IDC_3.
[7:0] is the LSByte of ATM_IDC_3.
ATM Idle Cell Match Mask Channel [0—3].
This 32-bit register defines which of the 32 bits
will be used for comparison between the idle
cell register and the header data in the ATM
framer. A value of 1 enables the comparison
with the corresponding bit in the ATM idle cell
register.
[31:24] is the MSByte of ATM_IDM_0.
[7:0] is the LSByte of ATM_IDM_0.
[31:24] is the MSByte of ATM_IDM_1.
[7:0] is the LSByte of ATM_IDM_1.
[31:24] is the MSByte of ATM_IDM_2.
[7:0] is the LSByte of ATM_IDM_2.
[31:24] is the MSByte of ATM_IDM_3.
[7:0] is the LSByte of ATM_IDM_3.
