TXSE0
TXSE0: Set and clear transmitting SE0 bit
1: Set transmitting SE0
0: Clear transmitting SE0
EP0STL: Endpoint 0 stall bit. This bit will be cleared automatically by hardware when SETUP packet is
received
1: Endpoint 0 will respond with a STALL to a valid transaction except SETUP
0: Endpoint 0 will not respond with a STALL to a valid transaction
EP1STL: Endpoint 1 stall bit
1: Endpoint 1 will respond with a STALL to a valid IN transaction
0: Endpoint 1 will not respond with a STALL to a valid IN transaction
WAKE: Wake-up bit
1: Set this bit to wake up host controller by placing USB bus into K state
0: Clear this bit to force USB bus leave K state
WKDIS: Wake-up disable bit. The WAKE bit has no effect if WKDIS bit is set to 1.
1: Disable remote wake-up capability
0: Enable remote wake-up capability
PWRDN: Power-down mode bit. Writing 1 to this bit will enter power-down mode
If USB suspend is detected, firmware can set this bit to enter power-down mode. In power-down
mode, crystal/resonator will stop. The PWRDN bit will be cleared automatically by hardware and
crystal/resonator will restart when the internal RC timer timeout (about 500ms). Firmware should
check buttons and photo position encoders of the mouse. If mouse status is not changed, Firmware
should set the PWRDN bit to enter power down mode again. Power consumption in suspend mode
depends on how much time the firmware checking mouse status changed. Hardware will also clear
PWRDN bit automatically when USB D+ or D- is toggled.
0: Normal mode, not power-down
Value on POR: “1 - 0 - 0 0 0 0”

Note 1: “R/W” means readable and writable bit. All reserved fields should not be changed by firmware.
Note 2: “-“ means unimplemented read as 0

RESUME
RESUME: Global resume bit
1: Global resume (USB D+/D- toggle) was detected
0: Global resume was not detected
SUSPD: Global suspend bit
1: Global suspend (USB idle more than 3ms) was detected
0: Global suspend was not detected
EP1TX: Endpoint 1 transmitting status bit
1: Data has been sent from endpoint 1
0: Data has not been sent from endpoint 1
EP0TX: Endpoint 0 transmitting status bit
1: Data has been sent from endpoint 0
0: Data has not been sent from endpoint 0
EP0RX: Endpoint 0 receiving status bit
