* @defgroup HspVmCmds HSP-VM commands
*
* The HSP-VM protocol is a synchronous request-reply protocol (except for
* one notable @ref CAMRTC_HSP_IRQ "exception"), where the CCPLEX VM client
* first writes a command word into a HSP shared mailbox and then waits for
* RCE FW to respond over the same mailbox. The responses are formatted
* with the same command ID as the associated requests, but the parameter
* values in each direction may differ.
*
* The protocol observes a state machine with state transitions triggered
* by message interactions. The protocol is described in more detail in
* the unit design documentation.
*
* The 32-bit HSP messages have the following format:
*

/**
* This is a @ref HspVmCmds "HSP-VM command" that signals the peer that
* some action is needed, for example, that new IVC messages are available
* in the receive queue of the peer. Unlike the other HSP-VM messages,
* the CAMRTC_HSP_IRQ message can be sent by either by the client
* (e.g. VM on CCPLEX) or RCE itself. The message is asynchronous and
* is never directly acknowledged by the peer.
*
* @note Each peer is required to check its IVC receive queue whenever
* any HSP message is received, not just when a CAMRTC_HSP_IRQ is received.
* Therefore, the CAMRTC_HSP_IRQ message need not be sent if another message
* for the peer is already pending in the HSP shared mailbox. For the
* same reason, it is permitted to overwrite an outgoing CAMRTC_HSP_IRQ
* message populated in a HSP mailbox with another outgoing HSP message.
*
* The HSP-VM protocol defines an optional mechanism to optimize the
* IVC wakeups. Each IVC channel is associated with one or more
* @ref camrtc_tlv_ivc_setup::channel_group "channel wakeup groups".
* The sender may use an associated HSP @ref HspSsReg "shared semaphore"
* to set @ref CAMRTC_HSP_SS_IVC_MASK "IVC group bits" to indicate that
* the receiver needs to inspect the IVC channels belonging to those
* groups for incoming messages.
*
* RCE FW uses bits [7:0] (@ref CAMRTC_HSP_SS_IVC_MASK "IVC group bits"
* << @ref CAMRTC_HSP_SS_FW_SHIFT) of the @ref HspSsReg
* "shared semaphore register" to signal outgoing messages to CCPLEX VM.
*
* CCPLEX VM uses bits [23:16] (@ref CAMRTC_HSP_SS_IVC_MASK
* "IVC group bits" << @ref CAMRTC_HSP_SS_VM_SHIFT) of the @ref HspSsReg
* "shared semaphore register" to signal outgoing messages to RCE FW.
*
* If no IVC group bits are set (sender likely does not support the
* optimization) or the receiver itself does not support the
* optimization, it must always check all IVC channels for incoming
* messages after receiving a HSP message.
*
* Other bits in the 32-bit @ref HspSsReg "shared semaphore register"
* are reserved for additional signalling between CCPLEX VM and RCE.
* These bits are currently unused.
*
* @pre IVC channels have been set up with @ref CAMRTC_HSP_CH_SETUP and
* RCE has been placed into active state with @ref CAMRTC_HSP_RESUME.
