Unused. Read = 0000b; Write = don’t care. | |
Bit3: | SOF: Start of Frame Interrupt |
| Set by hardware when a SOF token is received. This interrupt event is synthesized by hard- |
| ware: an interrupt will be generated when hardware expects to receive a SOF event, even if |
| the actual SOF signal is missed or corrupted. |
| This bit is cleared when software reads the CMINT register. |
| 0: SOF interrupt inactive. |
| 1: SOF interrupt active. |
Bit2: | RSTINT: Reset |
| Set by hardware when Reset signaling is detected on the bus. |
| This bit is cleared when software reads the CMINT register. |
| 0: Reset interrupt inactive. |
| 1: Reset interrupt active. |
Bit1: | RSUINT: Resume |
| Set by hardware when Resume signaling is detected on the bus while USB0 is in suspend |
| mode. |
| This bit is cleared when software reads the CMINT register. |
| 0: Resume interrupt inactive. |
| 1: Resume interrupt active. |
Bit0: | SUSINT: Suspend |
| When Suspend detection is enabled (bit SUSEN in register POWER), this bit is set by hard- |
| ware when Suspend signaling is detected on the bus. This bit is cleared when software |
| reads the CMINT register. |
| 0: Suspend interrupt inactive. |
| 1: Suspend interrupt active. |
