17.3.1.12 Port A External Port (GPIO_EXT_PORTA)
Used by the software to read values from the GPIO Port bits
MEM Offset (B0000C00) 0B0000C50h
Security_PolicyGroup
IntelRsvd False
Size 32 bits
Default 0000_0000h
Bits Access
Type
Default Description PowerWell ResetSignal
31:26 RO 6'b0 Reserved (RSV0)
25:0 RO 26'b0 External Port
(GPIO_EXT_PORTA)
When the Port is configured
as Input, then reading this
location reads the values on
the external signal. When the
data direction is set as
Output, reading this location
reads the Port data register

17.3.1.13 Synchronization Level (GPIO_LS_SYNC)
Controls if a level-sensitive interrupt type need to be synchronized to the system clock
MEM Offset (B0000C00) 0B0000C60h
Security_PolicyGroup
IntelRsvd False
Size 32 bits
Default 0000_0000h
Bits Access
Type
Default Description PowerWell ResetSignal
31:1 RO 31'b0 Reserved (RSV)
0 RW 1'b0 Synchronization Level
(GPIO_LS_SYNC)
Writing a 1 to this register
results in all level-sensitive
interrupts being synchronized
to the system clock.
0 Not Synchronized (default)
1 Synchronized
