DESCRIPTION
URT = 0:
URT = 1:
UART remains active when ISTR.PERIS = 1 and
the IDLE instruction is executed.

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

R/W
SP0 = 0:
SP0 = 1:
McBSP0 remains active when ISTR.PERIS = 1
and the IDLE instruction is executed.
McBSP0 is disabled when ISTR.PERIS = 1 and the
IDLE instruction is executed.
0
TIMER1 bit
TIM0
0†
R/W
TIM1 = 0:
TIM1 = 1:
TIMER1 remains active when ISTR.PERIS = 1
and the IDLE instruction is executed.
TIMER1 is disabled when ISTR.PERIS = 1 and the
IDLE instruction is executed.
0
TIMER0 bit
TIM0 = 0:
TIM0 = 1:
TIMER0 remains active when ISTR.PERIS = 1
and the IDLE instruction is executed.
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.
