All information provided in this document is subject to legal disclaimers.
Set to logic 1 immediately after the last bit of the transmitted data was sent out.
Set to logic 1, when a command terminates by itself e.g. when the
Set to logic 1, when bit HiAlert in register Status1Reg is set. In opposition to
Set to logic 1 if any error bit in the Error Register is set.
Description
Set to logic 1, Set1 defines that the marked bits in the register CommIRqReg
are set.
Set to logic 0, Set1 defines, that the marked bits in the register CommIRqReg
are cleared.
Set to logic 1 when the receiver detects the end of a valid datastream.
If the bit RxNoErr in register RxModeReg is set to logic 1, bit RxIRq is only set
to logic 1 when data bytes are available in the FIFO.
CommandReg changes its value from any command to the Idle Command.
If an unknown command is started, the CommandReg changes its content to
the idle state and the bit IdleIRq is set. Starting the Idle Command by the
μ-Controller does not set bit IdleIRq.
HiAlert, HiAlertIRq stores this event and can only be reset as indicated by bit
Set1.
LoAlert, LoAlertIRq stores this event and can only be reset as indicated by bit
Set1.
Set to logic 1 when the timer decrements the TimerValue Register to zero.
