OBUS8
Input
P4 The output port bus width select (OBUS8) selects
the output port interface bus width.
When OBUS8 is high, only ODAT[7:0] present valid
data and ODAT[15:8] are held low. When OBUS8
is low, all ODAT[15:0] outputs are used.
This input is only active if the SCIANY input is a
logic high.
OFCLK
Input
N5 The output port FIFO clock (OFCLK) is used to
transfer cells from the internal downstream cell
buffer to the PHY devices. OFCLK must cycle at a
52 MHz or lower instantaneous rate, but a high
enough rate to avoid a FIFO overflow. All SCI-
PHY/Any-PHY output port timing is relative to the
rising edge of OFCLK.
This input is only active if the SCIANY input is a
logic high.
