configuration_dedicated_io_13

         This register is used to control the electrical behavior and direction of Dedicated IO 13
Only reset by a cold reset (ignores warm reset).

Module Instance	Base Address	Register Address
`i_io48_pin_mux_dedicated_io_grp`	`0xFFD07200`	`0xFFD07334`

Offset: 0x134

Access: RW

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
