Also shown in this table is the internal connection of the ETRIG signals when the enhanced chip select
function is used.

1. If PCS4/5EN = 1 then A/B_T2CLK into the module is pulled up internally (enabling Div/8 clock, in gate mode).
2. If only PCS4EN=1, then A_T2CLK can be driven into B_T2CLK if PPM_SHORT[SH_T2CLK] is set.
3. If only PCS5EN=1 then A_T2CLK will be pulled up, if PPM_SHORT[SH_T2CLK] is set, then, B_T2CLK will be high
All of this is regardless of the Pull up/down state.
Note: The PPM shorting function has higher priority logic. If shorting is selected, then A_T2CLK → B_T2CLK. If A_T2CLK
