inlinevirtual |
Sets the state of the device. When debugging, it is unwise to rely on interrupt- driven I/O, however in normal use polling is extremely slow and CPU-intensive.
The debugger therefore will set the device to "debug state" by calling this function with the argument "true". In "debug state", any buffered input will be discarded, the device's interrupt masked, and the device will rely on polling only. This will be the default state.
When the device is set to "normal state" by calling this function with the argument "false", interrupts may be used, along with buffered input, and it is recommended that during blocking I/O a Semaphore is used to signal incoming interrupts, so that the blocked thread may go to sleep.
