MISC

13†

R/W

MISC bit

MISC = 0:

Miscellaneous modules remain active when

ISTR.PERIS = 1 and IDLE instruction is executed.

MISC = 1:

MIscellaneous module is disabled when

ISTR.PERIS = 1 and IDLE instruction is executed.

Miscellaneous modules include the XBSR, TIMEOUT Error Register,

XBCR, Timer Signal Selection Register, CLKOUT Select Register,

and Clock Mode Control Register.

EMIF

12†

R/W

EMIF bit

EMIF = 0:

EMIF module remains active when ISTR.PERIS = 1

and IDLE instruction is executed.

EMIF = 1:

EMIF module is disabled when ISTR.PERIS = 1 and

IDLE instruction is executed.

BIOST

11†

R/W

BIOS timer bit

BIOST = 0:

DSP/BIOS timer remains active when ISTR.PERIS = 1

and the IDLE instruction is executed.

BIOST = 1:

DSP/BIOS timer is disabled when ISTR.PERIS = 1 and

the IDLE instruction is executed.

WDT

10†

R/W

Watchdog timer bit

WDT = 0:

WDT remains active when ISTR.PERIS = 1

and the IDLE instruction is executed.

WDT = 1:

WDT is disabled when ISTR.PERIS = 1 and

the IDLE instruction is executed.

PIO

9†

R/W

Parallel GPIO bit

PIO = 0:

Parallel GPIO remains active when ISTR.PERIS = 1

(ISTR.[3]) and the IDLE instruction is executed.

PIO = 1:

Parallel GPIO 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.
