TX UTOPIA Clock Division. The selected TX UTOPIA clock
source is divided by the number programmed in these bits as
follows:
“00000000” = reserved
“00000001” = no division
“00000010” = divide by 2
“00000011” = divide by 3
“11111111” = divide by 255
These bits are meaningful only when the T8207 generates the
TX UTOPIA clock.
TX UTOPIA Clock Source Select. The source of the TX
UTOPIA clock is selected via these bits as follows:
“00” = cell bus write clock
“01” = reserved
“10” = pclk
“11” = mclk
These bits are meaningful only when the T8207 generates the
TX UTOPIA clock.
Reserved. Program to ‘0.’
TX UTOPIA Clock Enable. If this bit is ‘1,’ the T8207 gener-
ates the TX UTOPIA clock on the u_txclk pin. If this bit is ‘0,’
the u_txclk pin is configured as an input.
Reserved.
