note : Since RX_STRB and TX_STRB must be 8kHz, this implies that the
source clock (RX_I_CLK or TX_O_CLK) must be 128kHz. Furthermore,
since 128kHz is not derivable from CLK_I / 10 (or any of the active CLK
frequencies), this source clock must also be set up as an input (passive).

Description
In active mode, RX_STRB and/or TX_STRB = RX_I_CLK/16
In active mode, RX_STRB and/or TX_STRB = TX_O_CLK/16.
Active clock = CLK_I / 2
Active clock = CLK_I / 6
Active clock = CLK_I / 8
Active clock = CLK_I / 10
