S3C2440A RISC MICROPROCESSOR     INTERRUPT CONTROLLER 
  14-11 
INTERRUPT MASK (INTMSK) REGISTER 
This register also has 32 bits each of which is related to an interrupt source. If a specific bit is set to 1, the CPU 
does not service the interrupt request from the corresponding interrupt source (note that even in such a case, the 
corresponding bit of SRCPND register is set to 1). If the mask bit is 0, the interrupt request can be serviced. 
Register Address  R/W  Description  Reset Value

interrupt source will not be serviced. 
0 = Interrupt service is available. 
1 = Interrupt service is masked.
