oops, sorry I should have said TS7250.
As I suspected I already had the info I just could not find it.

DIO_8 is accessed via bit 1 of Port F in the EP9302. The Port F data
register is at address
location 0x8084_0030. The DDR address for this port is location
0x8084_0034.
The Pin 4 of the DIO1 Header, in the default configuration, is
accessed via bit 0 of Port C
in the EP9302. The address location 0x8084_0008 is Port C Data
Register and
0x8084_0018 is Port C Directon Register.
When accessing these registers, it is important not to change the
other bit positions in
these Port F registers. Other DIO1 Port functionality, used for
dedicated TS-7250
functions, utilize these same control registers. All accesses to
these registers should use
read-modify-write cycles.
! Warning
All pins on the DIO header use 0-3.3V logic levels. Do not drive
these lines to 5V.
thanks for you help.
