Host Change Of State Command (HCF_HOST_COS_CMD)
The HCF_HOST_COS_CMD flag signals a change in the state of the UMAC. A new state
is set in the ulApplicationCOS variable in the communication control block. The protocol
stack on the netX then toggles the NCF_HOST_COS_ACK flag in the netX
communication flags back acknowledging that the new state has been read. At
initialization time, this flag is cleared.
3
Host Change Of State Acknowledge (HCF_NETX_COS_ACK)
The HCF_NETX_COS_ACK flag is used by UMAC to indicate that the new state of the
protocol stack has been read. At initialization time, this flag is cleared.
4
Send Mailbox Command (HCF_SEND_MBX_CMD)
Both the HCF_SEND_MBX_CMD flag and the NCF_SEND_MBX_ACK flag are used
together to transfer non-cyclic packages between the UMAC and the protocol stack. At
initialization time, this flag is cleared.
5
Receive Mailbox Acknowledge (HCF_RECV_MBX_ACK)
Both the HCF_RECV_MBX_ACK flag and the NCF_RECV_MBX_CMD flag are used
together to transfer non-cyclic packages between the protocol stack and the UMAC. At
initialization time, this flag is cleared.
6
Process Data 0 Out Command (HCF_PD0_OUT_CMD)
Both the HCF_PD0_OUT_CMD flag and the NCF_PD0_OUT_ACK flag are used
together to transfer cyclic output data from the UMAC to the protocol stack. At
initialization time, this flag may be set, depending on the data exchanged mode.
7
Process Data 0 In Acknowledge (HCF_PD0_IN_ACK)
Both the HCF_PD0_IN_ACK flag and the NCF_PD0_IN_CMD flag are used together to
transfer cyclic input data from the protocol stack to the UMAC. At initialization time, this
flag may be set, depending on the data exchanged mode.
8
Process Data 1 Out Command (HCF_PD1_OUT_CMD, not supported yet)
Both the HCF_PD1_OUT_CMD flag and the NCF_PD1_OUT_ACK flag are used
together to transfer cyclic output data from the UMAC to the protocol stack. At
initialization time, this flag may be set, depending on the data exchanged mode.
9
Process Data 1 In Acknowledge (HCF_PD1_IN_ACK, not supported yet)
Both the HCF_PD1_IN_ACK flag and the NCF_PD1_IN_CMD flag are used together to
transfer cyclic input data from the protocol stack to the UMAC. At initialization time, this
flag may be set, depending on the data exchanged mode.
