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: outputs1 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.
