McASP Registers
22.4.1.20 Receiver Interrupt Control Register (RINTCTL)
The receiver interrupt control register (RINTCTL) controls generation of the McASP receive interrupt
(RINT). When the register bit(s) is set to 1, the occurrence of the enabled McASP condition(s) generates
RINT. The RINTCTL is shown in
and described in
. See
for a
description of the interrupt conditions.

Description
31-8
Reserved
0
Reserved. The reserved bit location always returns the default value. A value written to this field has no
effect. If writing to this field, always write the default value for future device compatibility.
7
RSTAFRM
Receive start of frame interrupt enable bit.
0
Interrupt is disabled. A receive start of frame interrupt does not generate a McASP receive interrupt
(RINT).
1
Interrupt is enabled. A receive start of frame interrupt generates a McASP receive interrupt (RINT).
6
Reserved
0
Reserved. The reserved bit location always returns the default value. A value written to this field has no
effect. If writing to this field, always write the default value for future device compatibility.
5
RDATA
Receive data ready interrupt enable bit.
0
Interrupt is disabled. A receive data ready interrupt does not generate a McASP receive interrupt
(RINT).
1
Interrupt is enabled. A receive data ready interrupt generates a McASP receive interrupt (RINT).
4
RLAST
Receive last slot interrupt enable bit.
0
Interrupt is disabled. A receive last slot interrupt does not generate a McASP receive interrupt (RINT).
1
Interrupt is enabled. A receive last slot interrupt generates a McASP receive interrupt (RINT).
3
RDMAERR
Receive DMA error interrupt enable bit.
0
Interrupt is disabled. A receive DMA error interrupt does not generate a McASP receive interrupt
(RINT).
1
Interrupt is enabled. A receive DMA error interrupt generates a McASP receive interrupt (RINT).
2
RCKFAIL
Receive clock failure interrupt enable bit.
0
Interrupt is disabled. A receive clock failure interrupt does not generate a McASP receive interrupt
(RINT).
1
Interrupt is enabled. A receive clock failure interrupt generates a McASP receive interrupt (RINT).
1
RSYNCERR
Unexpected receive frame sync interrupt enable bit.
0
Interrupt is disabled. An unexpected receive frame sync interrupt does not generate a McASP receive
interrupt (RINT).
1
Interrupt is enabled. An unexpected receive frame sync interrupt generates a McASP receive interrupt
(RINT).
0
ROVRN
Receiver overrun interrupt enable bit.
0
Interrupt is disabled. A receiver overrun interrupt does not generate a McASP receive interrupt (RINT).
1
Interrupt is enabled. A receiver overrun interrupt generates a McASP receive interrupt (RINT).
