Figure 7-6.
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 7-3.
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.
