Enum ps2::HostToControllerCommand

pub enum HostToControllerCommand {
    ReadFromInternalRAMByte0 = 32,
    WriteToInternalRAMByte0 = 96,
    DisablePort2 = 167,
    EnablePort2 = 168,
    TestPort2 = 169,
    TestController = 170,

}

Commands that can be sent to the PS/2 Controller.

The naming convention is device-centric:

• “Output” means sending data “out of the device to the host (CPU)”.
• “Input” means sending data “out of the host (CPU) into the device”.
  • Example: WriteByteToPort2InputBuffer instructs the host (CPU) to write a byte into port 2 of the device, so the device receives that byte as input.

Variants

ReadFromInternalRAMByte0 = 32

returns ControllerConfigurationByte

WriteToInternalRAMByte0 = 96

sets ControllerConfigurationByte

DisablePort2 = 167

sets ControllerConfigurationByte port2_clock_disabled

Note: only if 2 PS/2 ports supported

EnablePort2 = 168

clears ControllerConfigurationByte port2_clock_disabled

Note: only if 2 PS/2 ports supported

TestPort2 = 169

returns PortTestResult

Note: only if 2 PS/2 ports supported

TestController = 170

see PS2Controller::test

TestPort1 = 171

returns PortTestResult

DisablePort1 = 173

sets ControllerConfigurationByte port1_clock_disabled

EnablePort1 = 174

clears ControllerConfigurationByte port1_clock_disabled

WriteByteToPort2InputBuffer = 212

sends next byte to the second PS/2 port

Note: only if 2 PS/2 ports supported
