6.4.2 Warm Reset

A warm reset provides a limited reset to the device. Warm Reset is initiated by bringing only RESET low (TRST is maintained high through a warm reset). Warm reset sets certain portions of the device to their default state while leaving others unaltered. All pins are tri-stated with the exception of RESETOUT which remains active through the reset sequence, and RTCK/GP8[0]. During reset, GP8[0] is configured as a reserved function, and its behavior is not deterministic; the user should be aware that this pin will drive a level, and fact may toggle, during reset. RESETOUT is an output for use by other controllers in the system that indicates the device is currently in reset.

During an emulation, the emulator will maintain TRST high and hence only warm reset (not POR) is available during emulation debug and development.

A summary of the effects of Warm Reset is given below:

  • All internal logic (except for the emulation logic and the PLL logic) is reset to its default state
  • Internal memory is maintained through a warm reset
  • RESETOUT goes active
  • All device pins go to a high-impedance state
  • The RTC peripheral is not reset during a warm reset. A software sequence is required to reset the RTC
