PMITCTRL, Performance Monitors Integration mode Control register

The PMITCTRL characteristics are:

Purpose

Enables the Performance Monitors to switch from default mode into integration mode, where test software can control directly the inputs and outputs of the PE, for integration testing or topology detection.

Configuration

It is IMPLEMENTATION DEFINED whether PMITCTRL is implemented in the Core power domain or in the Debug power domain.

Implementation of this register is OPTIONAL.

Attributes

PMITCTRL is a 32-bit register.

Field descriptions

The PMITCTRL bit assignments are:

Bits [31:1]

Reserved, RES0.

IME, bit [0]

Integration mode enable. When IME == 1, the device reverts to an integration mode to enable integration testing or topology detection. The integration mode behavior is IMPLEMENTATION DEFINED.

The following resets apply:

• If the register is implemented in the Core power domain:

  • On a Cold reset, this field resets to 0.

  • On an External debug reset, the value of this field is unchanged.

  • On a Warm reset, the value of this field is unchanged.

• If the register is implemented in the External debug power domain:

  • On a Cold reset, the value of this field is unchanged.

  • On an External debug reset, this field resets to 0.

  • On a Warm reset, the value of this field is unchanged.

Accessing the PMITCTRL

PMITCTRL can be accessed through the external debug interface:

This interface is accessible as follows:

• When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus() and SoftwareLockStatus() accesses to this register are RO.
• When IsCorePowered(), !DoubleLockStatus(), !OSLockStatus() and !SoftwareLockStatus() accesses to this register are RW.
• Otherwise accesses to this register are IMPDEF.
