ARMEdit: SWI Calls

ARMEdit_TalkAck

ARMEdit_TalkAck
(SWI &4BC45)
Claim the most recently read message

On entry:R0 =client handle for this task

On exit:Registers preserved

Interrupts:Interrupt status is undefined
Fast interrupts are enabled

Processor mode:Processor is in SVC mode

Re-entrancy:SWI is not re-entrant

Use: After reading a message with ARMEdit_TalkRX, this call should be used to claim the message, and to prevent it being offered to other clients. This should be used before calling any other SWIs from this module.

If the message was sent by the ARMEdit module then calling this SWI has no effect; other clients still receive the message.
