8. Addendum: CCU 3000-I Specification
8.1. Changes to CCU3000
Instead of the Master/Slave IM bus Interface IM1 of
CCU3000, an I
2
C/IM bus Master is used.
Source 3 of the interrupt controller is not connected. Its
priority has to be set to ‘0’.
Source 4 of the interrupt controller is connected with
Port81 (Special Input). Falling edges of port 8, bit 1 gen-
erate interrupts if the priority of this interrupt source is not
set to 0. In I
2
C mode it is possible to switch I
2
C_CLK from
IM1_CLK_Pad to IM1_ID_Pad. Therefore two I
2
C
busses can be driven (see section 8.6. for details).
The CCU 3000-I is available in two different packages,
see pages
71 to 73. All other features are the same as
in CCU3000.
