Advanced Information DS41124A-page 61 PIC16C745/765 10.5.1.2 USB Interrupt Enable Register (UIE) The USB Interrupt Enable Register (UIE) contains enable bits for each of the interrupt sources within the USB. Setting any of these bits will enable the respec- tive interrupt source in the UIR register. The values in the UIE register only affect the propagation of an inter- rupt condition to the PIE1 register. Interrupt conditions can still be polled and serviced. REGISTER 10-2: USB INTERRUPT ENABLE REGISTER (UIE: 191h) U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 — — STALL UIDLE TOK_DNE ACTIVITY UERR USB_RST R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR reset bit7 bit0 bit 7-6: Unimplemented: Read as '0'. bit 5: STALL: Set to enable STALL interrupts. 1 = STALL interrupt enabled 0 = STALL interrupt disabled bit 4: UIDLE: Set to enable IDLE interrupts. 1 = IDLE interrupt enabled 0 = IDLE interrupt disabled bit 3: TOK_DNE: Set to enable TOK_DNE interrupts. 1 = TOK_DNE interrupt enabled 0 = TOK_DNE interrupt disabled bit 2(1): ACTIVITY: Set to enable ACTIVITY interrupts. 1 = ACTIVITY interrupt enabled 0 = ACTIVITY interrupt disabled bit 1: UERR: Set to enable ERROR interrupts. 1 = ERROR interrupt enabled 0 = ERROR interrupt disabled bit 0: USB_RST: Set to enable USB_RST interrupts. 1 = USB_RST interrupt enabled 0 = USB_RST interrupt disabled Note 1: This interrupt is the only interrupt active during UCTRL suspend = 1. |
