0 Do not clear the register.
1 Clear the register when bit is set from 0 to 1.
11-9 Reserved 0 Read returns 0. Writes have no effect.
8 ETSM Enable Transfer Status Mirrored
Mirror technique must be adjustable.
0 Disable mirror function for TSCB, LTBCC, LTBSM, TSMO1-4, TCCO1-4 and TOOFF.
1 Enable mirror function for TSCB, LTBCC, LTBSM, TSMO1-4, TCCO1-4 and TOOFF.
7-6 Reserved 0 Read returns 0. Writes have no effect.
5 SILE Status Interrupt Line Enable
Enable/Disable status line interrupt.
0 TU_Int0 is disabled.
1 TU_Int0 is enabled.
4 EILE Error Interrupt Line Enable
Enable/Disable error interrupt line.
0 TU_Int1 is disabled.
1 TU_Int1 is enabled.
3-2 Reserved 0 Read returns 0. Writes have no effect.
1 TUH Transfer Unit Halted
When halted, the Transfer Unit State Machine finishes the ongoing VBUSM access before it stops
working. After deassertion, the Transfer Unit State Machine continues at the point it was halted
before. No reconfiguration is required.
0 Transfer Unit not halted
1 Transfer Unit halted
Note: If the Transfer Unit State Machine halts, all mirroring registers contained the last
transfer not the current transfer information.
0 TUE Transfer Unit Enabled
Enable/Disable transfer unit.
0 Transfer Unit disabled, reset Transfer Unit State Machine, completion of the current VBUS transfer
cycle but data could be corrupt.
1 Transfer Unit enabled
Note: Before switching on the Transfer Unit, the registers must be set up. After re-enabling
of the Transfer Unit State Machine the contents of the module registers and the TCR is still
valid (assuming it was continuously powered).
