Bit 1: Transmit System Synchronization I/O Select (TSSYNCIOSEL)
0 = TSSYNCIO[8:1] are inputs on TSYNC/TSSYNCIO[8:1] pins.
1 = TSSYNCIO[8:1] are outputs synchronous to BPCLK1.
Bit 0: TSYNCn/TSSYNCIOn Pin Select (TSYNCSEL)
0 = TSYNCn is selected for TSYNC/TSSYNCIO[8:1] pins.
1 = TSSYNCIOn is selected for TSYNC/TSSYNCIO[8:1] pins.
Note: If TSYNCn is selected, control of TSYNCn (I/O) is via the
register. TSSYNCIOn is normally selected
when transmit elastic stores are enabled.
