OSIrqMask OS_EnableIrqMask( OSIrqMask intr );
intr | The IRQ interrupt cause to be enabled (expressed as a logical sum) |
This is the IRQ interrupt cause that was set before this function is called.
Sets IRQ interrupt parameters. In addition to the current setting, the designated cause's enable bit is enabled. Refer to OS_SetIrqMask
for a description of each cause and its corresponding value.
Note: Adds the specified causes in addition to the current settings. OS_SetIrqMask
is used to overwrite and set a specific cause. However, since there may be interrupt cause settings defined by the system which we do not want to change, it is best not to use the OS_SetIrqMask
function, since that overwrites all settings. In most cases, the OS_EnableIrqMask
function should be used to set the specific cause.
Operates on one of the IO registers, IE (Interrupt Enable).
