Table 30.
All bits in the ComIrqReg register are cleared by software.
Bit Symbol
Value Description
7
Set1
1
indicates that the marked bits in the ComIrqReg register are set
0
indicates that the marked bits in the ComIrqReg register are cleared
6
TxIRq
1
set immediately after the last bit of the transmitted data was sent out
5
RxIRq
1
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
4
IdleIRq
1
If a command terminates, for example, when the CommandReg changes
its value from any command to the Idle command (see
Table 149 on
page 67
)
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
3
HiAlertIRq
1
the Status1Reg register’s HiAlert bit is set
in opposition to the HiAlert bit, the HiAlertIRq bit stores this event and
can only be reset as indicated by the Set1 bit in this register
2
LoAlertIRq
1
Status1Reg register’s LoAlert bit is set
in opposition to the LoAlert bit, the LoAlertIRq bit stores this event and
can only be reset as indicated by the Set1 bit in this register
1
ErrIRq
1
any error bit in the ErrorReg register is set
0
TimerIRq
1
the timer decrements the timer value in register TCounterValReg to zero
9.3.1.6
