It is also possible to reset the device by asserting the RESET_N pin. This pin has an internal pul-
lup, and does not need to be driven externally when negated.
reset sources supported by the Reset Controller.

In addition to the listed reset types, the JTAG can keep parts of the device statically reset
through the JTAG Reset Register. See JTAG documentation for details.
Table 13-3.
When a Reset occurs, some parts of the chip are not necessarily reset, depending on the reset
source. Only the Power On Reset (POR) will force a reset of the whole chip.
