5.3.2
This register enables the individual interrupt sources' ability
to clear posted interrupts.
When bits in this register are read, a '1' is returned for every
bit position that has a corresponding posted interrupt. When
bits in this register are written with a '0' and ENSWINT is not
set, posted interrupts are cleared at the corresponding bit
positions. If there is no posted interrupt, there is no effect.
When bits in this register are written with a '1' and ENSWINT
is set, an interrupt is posted in the interrupt controller.
Bit 7: Endpoint3. Read '0', no posted interrupt for USB
Endpoint3. Read '1', posted interrupt present for USB
Endpoint3.
Write 0 AND ENSWINT = 0. Clear posted interrupt if it
exists.
Write 1 AND ENSWINT = 0. No effect.
Write 0 AND ENSWINT = 1. No effect.
Write 1 AND ENSWINT = 1. Post an interrupt for USB
Endpoint3.
Bit 6: Endpoint2. Read '0', no posted interrupt for USB
Endpoint2. Read '1', posted interrupt present for USB
Endpoint2.
Write 0 AND ENSWINT = 0. Clear posted interrupt if it
exists.
Write 1 AND ENSWINT = 0. No effect.
Write 0 AND ENSWINT = 1. No effect.
Write 1 AND ENSWINT = 1. Post an interrupt for USB
Endpoint2.
Bit 5: Endpoint1. Read '0', no posted interrupt for USB
Endpoint1. Read '1', posted interrupt present for USB
Endpoint1.
Write 0 AND ENSWINT = 0. Clear posted interrupt if it
exists.
Write 1 AND ENSWINT = 0. No effect.
Write 0 AND ENSWINT = 1. No effect.
Write 1 AND ENSWINT = 1. Post an interrupt for USB
Endpoint1.
