  1. gpio4_28 is multiplexed with EMU0 and gpio4_29 is multiplexed with EMU1. These pins will be sampled at reset release by the test and emulation logic. Therefore, if they are used as GPIO pins, they must return to the high state whenever the device enters reset. This can be controlled by logic driven from rstoutn. After the device exits reset (indicated by rstoutn rising), these can return to GPIO mode.
