## Pcd8259LegacyModeMask defines the default mask value for platform. This value is determined\r
# 1) If platform only support pure UEFI, value should be set to 0xFFFF or 0xFFFE;\r
# Because only clock interrupt is allowed in legacy mode in pure UEFI platform.\r
# b) If all thunk call provied by CSM binary do not require legacy interrupt support, value should be set\r
# to 0xFFFF or 0xFFFE.\r
#\r
- # Because the value is used as intialization value, PCD's type should be FixedAtBuild.\r
- #\r
# The default value of legacy mode mask could be changed by EFI_LEGACY_8259_PROTOCOL->SetMask(). But it is rarely\r
# need change it except some special cases such as when initializing the CSM binary, it should be set to 0xFFFF to \r
# mask all legacy interrupt. Please restore the original legacy mask value if changing is made for these special case.\r
## Pcd8259LegacyModeEdgeLevel defines the default edge level for legacy mode's interrrupt controller.\r
