6.4.12.4 Telecom Status/Control Register
The following table shows the Telecom Status/Control Register details.
6.4.12.5 Interrupt Mask and Map Registers
Each interrupt signal of the External Interrupt Status Register, Processor Hot Status/Control
Register or Telecom Status/Control Register can be mapped to one of the CPU_IRQ_X_
interrupt or any IRQ Frame number of the serialized IRQ protocol.
Multiple interrupt sources may share the same CPU_IRQ_X_ or the same IRQ Frame. In this
case all interrupt sources need to be of type “level active low”.
Each Interrupt source has an Interrupt Mask and Map Register.
