| 4 | Description: Make it possible to switch the PicoLCD device between LCD | |
| 5 | (firmware) and bootloader (flasher) operation modes. | |
| 6 | ||
| 7 | Reading: returns list of available modes, the active mode being | |
| 8 | enclosed in brackets ('[' and ']') | |
| 9 | ||
| 10 | Writing: causes operation mode switch. Permitted values are | |
| 0b5adf92 | 11 | the non-active mode names listed when read. |

| 13 | Note: when switching mode the current PicoLCD HID device gets | |
| 0b5adf92 BP |
14 | disconnected and reconnects after above delay (see attribute |
| 15 | operation_mode_delay for its value). | |

| 21 | Description: Delay PicoLCD waits before restarting in new mode when | |
| 22 | operation_mode has changed. | |
| 23 | ||
| 24 | Reading/Writing: It is expressed in ms and permitted range is | |
| 25 | 0..30000ms. | |

| 31 | Description: Make it possible to adjust defio refresh rate. | |
| 32 | ||
| 33 | Reading: returns list of available refresh rates (expressed in Hz), | |
| 34 | the active refresh rate being enclosed in brackets ('[' and ']') | |
| 35 | ||
| 36 | Writing: accepts new refresh rate expressed in integer Hz | |
| 37 | within permitted rates. | |
| 38 | ||
| 39 | Note: As device can barely do 2 complete refreshes a second | |
| 40 | it only makes sense to adjust this value if only one or two | |
| 41 | tiles get changed and it's not appropriate to expect the application | |
| 08559657 | 42 | to flush its tiny changes explicitly at higher than default rate. |
