NOTE
PCS_IN[3:0] are driven from the QSMCM module. PCS_OUT[7:0] values
are driven by the corresponding PCS[7:0] pads. If all of the PCS enable bits
PCS4EN, PCS5EN, PCS6EN and PCS7EN bits are zero, PCS[3:0] will be
driven directly by the QSMCM module. If one or more of these enable bits
is set, the enhanced PCS function is selected, and the enabled pads drive
PCS_OUT[7:0] value, as shown in
.
details the functionality of the A_T2CLK/PCS5 and B_T2CLK/PCS4 pads dependent on the
values of PDMCR2[PCS5EN], PDMCR2[PCS4EN] and SHORT_REG [SH_T2CLK]. Also shown in this
table is the internal connection of the TPU signals when the enhanced chip select function is used.
