resume interrupt (RESI). ERESI = 1 enables interrupts
generated by the resume event.
RESI - Wakeup interrupt flag. EICON.4 = 1 indicates a
negative transition was detected at the WAKEUP# pin, or
that USB has activity resumed from the suspended state.
EICON.4 = 1 must be cleared by software before exiting the
interrupt service routine, otherwise the interrupt occurs
again. Setting EICON.4=1 in software generates a wakeup
interrupt, if enabled.
has detected a low to high transition. INT6 will remain active
until cleared by writing a 0 to this bit. Setting this bit in
software generates an INT6 interrupt in enabled.
Reserved. Read as 0.
ERESI - Enable resume interrupt. ERESI = 0 disables
INT6 - External interrupt 6. When INT6 = 1, the INT6 pin
