ComIrqReg register
Interrupt request bits.
Table 30.
Bit
Symbol
Access
Table 31.
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 150 on
page 68
)
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
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
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
ComIrqReg register (address 04h); reset value: 14h bit allocation
