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.

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.

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.
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.
When level mode is selected, write 0/1 to this bit will set the level of GPIO04.
0: outputs 0 when in output mode.
