I believe the correct bitmap for the control register is:

`
//
// Bit: | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
// | --- | --- | --- | --- | ------- | ------- | -------- | ------- |
// Value: | [SLEEP] | / | / | [OD_EN] | |[A_SCAN] | | [IO_OE] |
// | --- | --- | --- | --- | ------- | ------- | -------- | ------- |
// Default: | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
