Bits 31:16 Reserved, must be kept at reset value.
Bits 15:13 PU[15:13]: Port PC[y] pull-up (y = 13 to 15)
When set, each bit activates the pull-up on PC[y] when both APC bits are set in PWR control
register 3 (PWR_CR3) and in PWR CPU2 control register 3 (PWR_C2CR3). The pull-up is
not activated if the corresponding PC[y] bit is also set.
Bits 12:7 Reserved, must be kept at reset value.
Bits 6:0 PU[6:0]: Port PC[y] pull-up (y = 0 to 6)
When set, each bit activates the pull-up on PC[y] when both APC bits are set in PWR control
register 3 (PWR_CR3) and in PWR CPU2 control register 3 (PWR_C2CR3). The pull-up is
not activated if the corresponding PC[y] bit is also set.
