Mode Select (MODE B)
—During the bootstrap process MODE A

Port H GPIO (2)
—This pin is a General Purpose I/O (GPIO) pin after
the bootstrap process has completed.
RESET
K4
39
Input
Reset (RESET)
—This input is a direct hardware reset on the
processor. When RESET is asserted low, the device is initialized and
placed in the Reset state. A Schmitt trigger input is used for noise
immunity. When the RESET pin is deasserted, the initial chip operating
mode is latched from the MODE A, MODE B, and MODE C pins.
To ensure complete hardware reset, RESET and TRST should be
asserted together. The only exception occurs in a debugging
environment when a hardware reset is required and it is necessary not
to reset the JTAG/Enhanced OnCE module. In this case, assert
RESET, but do not assert TRST.
