Polling Enable Receive Channel [A—D]. If
set to 1, receive polling mode is enabled.
Reserved. These bits must be written to their
reset default value (00).
Polling Receive Address Channel [A—D].
Receive polling address.
Reserved. This bit must be written to its reset
default value (0).
Clock Mode Receive Channel [A—D].
Defines if the RxCLK[A—D] is sourced or sunk.
If this bit = 1, the clock is sourced, and then
(1) the corresponding Tx clock is used as
RxCLK[A—D], and (2) this clock is also sent out
of the device via RxCLK[A—D].
If this bit = 0, CLOCK_MODE_Rx[A—D] is
sunk, and then RxCLK[A—D] acts as an input.
Default is sink.
Parity Receive Channel [A—D]. Defines if odd
(bit = 1) or even (bit = 0) parity is generated for
the data transmitted across the UTOPIA PHY
Rx interface. Default is odd.
ATM Packet Size Receive Channel [A—D].
Defines how many bytes are received per ATM
cell. Default is 53 bytes. Valid only when traffic
type is ATM cells.
Page 86 and page 87 give details of the func-
tion of this bit.
0 = standard 53-byte (also 54-byte and 56-byte)
ATM cell modes.
1 = 52-byte ATM cell mode (HEC omitted).
Traffic Type Receive Channel [A—D]. Config-
ures channel to receive either ATM cells or
packets.
