DESCRIPTION

URT

8†

R/W

UART bit

URT = 0:

UART remains active when ISTR.PERIS = 1 and

the IDLE instruction is executed.

URT = 1:

UART is disabled when ISTR.PERIS = 1 and the IDLE

instruction is executed.

I2C

7†

R/W

I2C bit

I2C = 0:

I2C remains active when ISTR.PERIS = 1 and

the IDLE instruction is executed.

I2C = 1:

I2C is disabled when ISTR.PERIS = 1 and the IDLE

instruction is executed.

6†

R/W

ID bit

ID = 0:

ID remains active when ISTR.PERIS = 1 and the

IDLE instruction is executed.

ID = 1:

ID is disabled when ISTR.PERIS = 1 and the IDLE

instruction is executed.

5†

R/W

IO bit

IO = 0:

GPIO remains active when ISTR.PERIS = 1 and

the IDLE instruction is executed.

IO = 1:

GPIO is disabled when ISTR.PERIS = 1 and the IDLE

instruction is executed.

Reserved

R/W

Reserved

SP1

3†

R/W

McBSP1 bit

SP1 = 0:

McBSP1 remains active when ISTR.PERIS = 1

and the IDLE instruction is executed.

SP1 = 1:

McBSP1 is disabled when ISTR.PERIS = 1 and the

IDLE instruction is executed.

SP0

2†

R/W

McBSP0 bit

SP0 = 0:

McBSP0 remains active when ISTR.PERIS = 1

and the IDLE instruction is executed.

SP0 = 1:

McBSP0 is disabled when ISTR.PERIS = 1 and the

IDLE instruction is executed.

TIM1

1†

R/W

TIMER1 bit

TIM1 = 0:

TIMER1 remains active when ISTR.PERIS = 1

and the IDLE instruction is executed.

TIM1 = 1:

TIMER1 is disabled when ISTR.PERIS = 1 and the

IDLE instruction is executed.

TIM0

0†

R/W

TIMER0 bit

TIM0 = 0:

TIMER0 remains active when ISTR.PERIS = 1

and the IDLE instruction is executed.

TIM0 = 1:

TIMER0 is disabled when ISTR.PERIS = 1 and the

IDLE instruction is executed.

† If the peripheral is already in IDLE, setting PERI (bit 3 of ICR) to 0 and executing the IDLE instruction will wake up all peripherals, and PICR bit

settings will be ignored. If PERIS (bit 3 of ISTR) = 1, executing the IDLE instruction will wake up the peripheral if its PICR bit is 0.
