Receive Data Channel B. Used to transport data out of the
UTOPIA PHY Rx block. RxDATA[B][15:0] is only valid when
RxENB[B] is asserted, and is updated on the rising edge of
RxCLK[B]. Note that RxDATA[B][15:0] is used in various UTO-
PIA modes. In U2 or U2+, all 16 bits are valid. In U3 or U3+ (8-
bit mode), only bits 15 to 8 are valid.
In U3 or U3+ (32-bit mode), RxDATA[B][15:0] forms the least sig-
nificant 16 bits of the combined data bus (bits 15 to 0), and
RxDATA[A][15:0] forms the most significant 16 bits of the com-
bined data bus (bits 31 to 16). In this mode, channel B port must
be provisioned to idle.
In this mode, RxDATA[B][15:0] is valid when RxENB[A] is
asserted, and RxDATA[B][15:0] is updated on the rising edge of
RxCLK[A].
Note: [15:0] refers to a 16-bit data bus (15 = MSB, 0 = LSB).
Receive Data Channel C. Used to transport data out of the
UTOPIA PHY Rx block. RxDATA[C][15:0] is only valid when
RxENB[C] is asserted, and is updated on the rising edge of
RxCLK[C]. Note that RxDATA[C][15:0] is used in various UTO-
PIA modes. In U2 or U2+, all 16 bits are valid. In U3+ (8-bit
mode), only bits 15 to 8 are valid.
In U3 or U3+ (32-bit mode), channel C port must be provisioned
to idle mode.
Note: [15:0] refers to a 16-bit data bus (15 = MSB, 0 = LSB).
