Peripherals can be frozen when a core is put into debug halt if a suspend signal is 
associated between a core and a peripheral.  This can be useful for debug of peripherals
which have running timers, watchdogs, or DMAs.

Suspend CPU mapping:
============================
Suspend Router: @APB:0x9D300000 | @AXI:0x4C:0x3D300000   

CPU Suspend Input mappings:
-----------------------------
0     => unused
1,2   => A72-0,A72-1
9     => C7x
17,18 => MCU-R50, MCU-R51
19,20 => MAIN0-R50, MAIN0-R51
21,22 => MAIN1-R50, MAIN1-R51
23/24 => C660, C661

Peripheral Outputs (0-127 slots):
----------------------------------
main timers main_0 to main_19 are mapped to slots 58 to 77 
mcu timers mcu_0 to mcu_9 are mapped to slots 89 through 98

MCU-TIMER0 is in slot 89  (89+1) x 4 = 360 = 0x168 
  @APB:0x9D300168         - debug address plane
  @AXI:0x4C:0x3D300168    - 64bit-system address

stop timer if "MCU-R50" is halted by writing:
  Data.Set EAPB:0x9D300168 %LE %Long (0x10000|17.)
  or Data.Set AXI:0x4C:0x3D300168 %LE %Long (0x10000|17.)

stop timer if "A72-0" is halted by writing:
  Data.Set EAPB:0x9D300168 %LE %Long (0x10000|1.)
  or Data.Set AXI:0x4C:0x3D300168 %LE %Long (0x10000|1.)
