6.5.2 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 3-stated .
During emulation, the emulator will maintain TRST high and hence only warm reset (not POR) is available
during emulation debug and development.
RTCK is maintained active through a warm reset.
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
• All device pins go to a high-impedance state
