STM32F411/RM0383 bad GPIOA->MODER reset value

Hello,

 

page 153 tells:

8.4.1 GPIO port mode register (GPIOx_MODER) (x = A..E and H)
Address offset: 0x00
Reset values:
· 0x0C00 0000 for port A

 

This does not make sense and a look at a real device after reset gives:

(gdb) p /x GPIOA->MODER
$1 = 0xa8000000
