OTG timers customizing
It is possible to refine some OTG timers thanks to the OTGTCON register that contains the
PAGE bits to select the timer and the VALUE bits to adjust the value. User should refer to lastest
releases of the OTG specification to select compliant timings.
The USB connection is detected by the VBUS pad, thanks to the following architecture:
• PAGE=00b: AWaitVrise time-out. [OTG]. In Host mode, once VBUSREQ has been set to “1”,
• PAGE=01b: VbBusPulsing. [OTG]. In Device mode, this delay corresponds to the pulse
• PAGE=10b: PdTmOutCnt. [OTG]. In Device mode, when a SRP has been requested to be
• PAGE=11b: SRPDetTmOut. [OTG]. In Host mode, this delay is the minimum pulse duration
if no VBUS is detected on VBUS pin after this AWaitVrise delay then the VBERRI error flag is
set.
duration on Vbus during a SRP.
sent by the firmware, this delay is waited by the hardware after VBUS has gone below the
“session_valid” threshold voltage and before initiating the first pulse. This delay should be
considered as an approximation of USB lines discharge (pull-down resistors vs. line
capacitance) in order to wait that VBUS has gone below the “b_session_end” threshold
voltae, as defined in the OTG specification.
