GPIO0 Output Data Register ⎯ Index F1h (This byte could be also written by base address + 6)
Bit
Name
R/W Reset Default
Description
GPIO07 supports pulse mode.
When pulse mode is selected, write “1” to this bit will assert a pulse from
GPIO07. Auto clear when pulse is finished.
7
GPIO07_VAL R/W 5VSB 0 When level mode is selected, write 0/1 to this bit will set the level of GPIO07.
0: outputs 0 when in output mode.
1: outputs 1 when in output mode. GPIO07 will be tri-state if GPIO07_DRV is
clear to “0”.
GPIO06 supports pulse mode.
When pulse mode is selected, write “1” to this bit will assert a pulse from
GPIO06. Auto clear when pulse is finished.
6
GPIO06_VAL R/W 5VSB 0 When level mode is selected, write 0/1 to this bit will set the level of GPIO06.
0: outputs 0 when in output mode.
1: outputs 1 when in output mode. GPIO06 will be tri-state if GPIO06_DRV is
clear to “0”.
GPIO05 supports pulse mode.
When pulse mode is selected, write “1” to this bit will assert a pulse from
GPIO05. Auto clear when pulse is finished.
5
GPIO05_VAL R/W 5VSB 0 When level mode is selected, write 0/1 to this bit will set the level of GPIO05.
0: outputs 0 when in output mode.
1: outputs 1 when in output mode. GPIO05 will be tri-state if GPIO05_DRV is
clear to “0”.
GPIO04 supports pulse mode.
When pulse mode is selected, write “1” to this bit will assert a pulse from
GPIO04. Auto clear when pulse is finished.
4
GPIO04_VAL R/W 5VSB 0 When level mode is selected, write 0/1 to this bit will set the level of GPIO04.
0: outputs 0 when in output mode.
1: outputs 1 when in output mode. GPIO04 will be tri-state if GPIO04_DRV is
clear to “0”.1: GPIO04 outputs 1 when in output mode.
0: GPIO03 outputs 0 when in output mode.
3
GPIO03_VAL R/W 5VSB 1
1: GPIO03 outputs 1 when in output mode.
0: GPIO02 outputs 0 when in output mode.
2
GPIO02_VAL R/W 5VSB 1
1: GPIO02 outputs 1 when in output mode.
0: GPIO01 outputs 0 when in output mode.
1
GPIO01_VAL R/W 5VSB 1
1: GPIO01 outputs 1 when in output mode.
0: GPIO00 outputs 0 when in output mode.
0
GPIO00_VAL R/W 5VSB 1
1: GPIO00 outputs 1 when in output mode.
