1) Pull-down with I_PORST relevant is always activated when a primary supply monitor detects a violation.
2) Valid additionally after deactivation of PORST until the internal reset phase has finished. See the SCU chapter for details.
3) See the SCU_IOCR register description.
4) Depends on JTAG/DAP selection with TRST.
In case of leakage test (PORST = 0 and TESTMODE = 0), the pull-down of the TRST pin is switched off. In case
of an user application (TESTMODE = 1), the pull-down of the TRST is always switched on.
