+ ## Pcd8259LegacyModeMask defines the default mask value for platform. This\r

+ # 1) If platform only support pure UEFI, value should be set to 0xFFFF or\r
+ # 0xFFFE; Because only clock interrupt is allowed in legacy mode in pure\r
+ # UEFI platform.\r
+ # 2) If platform install CSM and use thunk module:\r
+ # a) If thunk call provided by CSM binary requires some legacy interrupt\r
+ # support, the corresponding bit should be opened as 0.\r
+ # For example, if keyboard interfaces provided CSM binary use legacy\r
+ # keyboard interrupt in 8259 bit 1, then the value should be set to\r
+ # 0xFFFC.\r
+ # b) If all thunk call provied by CSM binary do not require legacy\r
+ # interrupt support, value should be set to 0xFFFF or 0xFFFE.\r
+ #\r
+ # The default value of legacy mode mask could be changed by\r
+ # EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely need change it\r
+ # except some special cases such as when initializing the CSM binary, it\r
+ # should be set to 0xFFFF to mask all legacy interrupt. Please restore the\r
