LPM control and status register
Structs§
- LPMCS
Rrs - LPM control and status register
Enums§
- LPMACK
- LPM Token acknowledge enable The NYET/ACK will be returned only on a successful LPM transaction: No errors in both the EXT token and the LPM token (else ERROR) A valid bLinkState = 0001B (L1) is received (else STALL) This bit contains the device answer to the LPM transaction. It mast be evaluated following the L1REQ interrupt.
Type Aliases§
- BESL_R
- Field
BESL
reader - BESL value Device mode These bits contain the BESL value received with last ACKed LPM Token Host mode These bits contain the BESL value transmitted with the LPM transaction - LPMACK_
R - Field

It mast be evaluated following the L1REQ interrupt. - LPMEN_R
- Field
LPMEN
reader - LPM support enable Device mode This bit is set by the software to enable the LPM support within the USB device. If this bit is at ’0 no LPM transactions are handled. Host mode Software sets this bit to transmit an LPM transaction to device. This bit is cleared by hardware, simultaneous with L1REQ flag set, when device answer is received - LPMEN_W
- Field
