Table 5. Signal details (continued)
The WKPCFG pin is applied at the assertion of the internal reset
signal (assertion of RSTOUT), and is sampled 4 clock cycles
before the negation of the RSTOUT pin.
The value is used to configure whether the eTPU and eMIOS
pins are connected to internal weak pull up or weak pull down
devices after reset. The value latched on the WKPCFG pin at
reset is stored in the Reset Status Register (RSR), and is
updated for all reset sources except the Debug Port Reset and
Software External Reset.
0: Weak pulldown applied to eTPU and eMIOS pins at reset
1: Weak pullup applied to eTPU and eMIOS pins at reset.

Register 1 is used to select the IRQ[0:15] pins as inputs to the
IRQs.
