DRSYNCR=B_0x0
Log message interval register
| LSI | Log Sync Interval This field indicates the periodicity of the automatically generated SYNC message when the PTP node is Master. Allowed values are -15 to 15. Negative value must be represented in 2’s-complement form. For example, if the required value is -1, the value programmed must be 0xFF. |
| DRSYNCR | Delay_Req to SYNC Ratio In Slave mode, it is used for controlling frequency of Delay_Req messages transmitted. Others: Reserved, must not be used The master sends this information (logMinDelayReqInterval) in the DelayResp PTP messages to the slave. The reception processes this value from the received DelayResp messages and updates this field accordingly. In the Slave mode, the host must not write/update this register unless it has to override the received value. In Master mode, the sum of this field and logSyncInterval (LSI) field is provided in the logMinDelayReqInterval field of the generated multicast Delay_Resp PTP message. 0 (B_0x0): DelayReq generated for every received SYNC 1 (B_0x1): DelayReq generated every alternate reception of SYNC |
| LMPDRI | Log Min Pdelay_Req Interval This field indicates logMinPdelayReqInterval of PTP node. This is used to schedule the periodic Pdelay request packet transmission. Allowed values are -15 to 15.Negative value must be represented in 2’s-complement form. For example, if the required value is -1, the value programmed must be 0xFF. |
