indicates that the marked bits in the ComIrqReg register are set
indicates that the marked bits in the ComIrqReg register are cleared
set immediately after the last bit of the transmitted data was sent out
receiver has detected the end of a valid data stream
if the RxModeReg register’s RxNoErr bit is set to logic 1, the RxIRq bit is
only set to logic 1 when data bytes are available in the FIFO
if a command terminates, for example, when the CommandReg changes
its value from any command to the Idle command (see
page
if an unknown command is started, the CommandReg register
Command[3:0] value changes to the idle state and the IdleIRq bit is set
the microcontroller starting the Idle command does not set the IdleIRq bit
the Status1Reg register’s HiAlert bit is set
the HiAlertIRq bit stores this event and can only be reset as indicated by
the Set1 bit in this register
Status1Reg register’s LoAlert bit is set
the LoAlertIRq bit stores this event and can only be reset as indicated by
the Set1 bit in this register
any error bit in the ErrorReg register is set
the timer decrements the timer value in register TCounterValReg to zero
