21 Configurable pull that is enabled and pulled down after reset.
22 The ALLPST signal is available only on the 196 MAPBGA package and allows limited debug trace functionality compared to the 256
MAPBGA package.
23 If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The GPIO module is not responsible for assigning these
pins.
24 VSTBY is for optional standby lithium battery. If not used, connect to EVDD.
