6.4.12.4 Telecom Status/Control Register
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. See the table below.
Table 6-61 Telecom Status/Control Register
Address Offset: 0x22
Bit Signal Description Default Access
0 CH1_CLK1A_IN Clock CLK1A of Chassis 1 has changed
state from static to toggle or toggle to static. 0 LPC: r/w1c
1 CH1_CLK1B_IN Clock CLK1A of Chassis 1 has changed
state from static to toggle or toggle to static. 0 LPC: r/w1c
2 - Telecom timeout occurred. 0 LPC: r/w1c
3 - Reserved - r
7:4 - Counter of Telecom timeout occurred.
Clearing bit 2 of this register also clears this
counter. 0 LPC: r
