Bit Field Value Description
3 RESET 0-1 This bit is set when Reset signaling is present on the bus. Note: This bit is Read/Write in Host
Mode, but read-only in Peripheral Mode.
2 RESUME 0-1 Set to generate Resume signaling when the controller is in Suspend mode. The bit should be
cleared after 10 ms (a maximum of 15 ms) to end Resume signaling. In Host mode, this bit is also
automatically set when Resume signaling from the target is detected while the USB controller is
suspended.
1 SUSPENDM 0-1 In Host mode, this bit should be set to enter Suspend mode. In Peripheral mode, this bit is set on
entry into Suspend mode. It is cleared when the interrupt register is read, or the RESUME bit is set.
0 ENSUSPM 0-1 Set to enable the SUSPENDM output.
The Interrupt Register for Endpoint 0 Plus Transmit Endpoints 1 to 4 (INTRTX) is shown in Figure 62 and
described in Table 63 .
