5.3.3
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 was not a 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 con-
troller.
Bit 5: USB_WAKE. Read ‘0’, no posted interrupt for USB
wakeup. Read ‘1’, posted interrupt present for USB wakeup.
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
wakeup.
Bit 4: Endpoint8. Read ‘0’, no posted interrupt for USB
Endpoint8. Read ‘1’, posted interrupt present for USB
Endpoint8.
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
Endpoint8.
Bit 3: Endpoint7. Read ‘0’, no posted interrupt for USB
Endpoint7. Read ‘1’, posted interrupt present for USB
Endpoint7.
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.
