1.1.3 SYSTEM REGISTERS
Following is the description of System Registers.
For PORT0 to PORT5 Registers, please refer to
I/O Port Chapter.
1.1.3.1 Central Interrupt Control Register
This Register CICR is located in the system Regis-
ter Group at the address R230 (E6h). Please refer
to “INTERRUPT” and “DMA” chapters in order to
get the background of the ST9 interrupt philoso-
phy.

b7 = GCEN:
Global Counter Enable. This bit is the
Global Counter Enable of the Multifunction Timers.
The GCEN bit is ANDed with the CE (Counter En-
able) bit of the Timer Control Register (explained in
the Timer chapter) in order to enable the Timers
when both bits are set. This bit is set after the Re-
set cycle.
b6 = TLIP:
Top Level Interrupt Pending. This bit is
automatically set when a Top Level Interrupt Re-
quest is recognized. This bit can also be set by
Software in order to simulate a Top Level Interrupt
Request.
b5 = TLI:
Top Level Interrrupt bit. When this bit is
set, a Top Level interrupt request is acknowledged
depending on the IEN bit and the TLNM bit (in
Nested Interrupt Control Register). If the TLM bit is
reset the top level interrupt acknowledgement de-
pends on the TLNM alone.
b4 = IEN:
Enable Interrupt. This bit, (when set), al-
lows interrupts to be accepted. When reset no in-
terrupts other than the NMI can be acknowledged.
It is cleared by interrupt acknowledgement for con-
current mode and set by interrupt return (iret). It
can be managed by hardware and software (ei
and di instruction).
b3 = IAM:
Interrupt Arbitration Mode. This bit cov-
ers the selection of the two arbitration modes, the
Concurrent Mode being indicated by the value “0”
and the Fully Automatic Nested Mode by the value
“1”. This bit is under software control.
b2-b0 = CPL2-CPL0:
Current Priority Level. These
three bits record the priority level of the interrupt
presently under service (i.e. the Current Priority
Level, CPL). For these priority levels 000 is the
highest priority and 111 is the lowest priority. The
CPL bits can be set by hardware or software and
give the reference by which following interrupts are
either left pending or able to interrupt the current
interrupt. When the present interrupt is replaced by
one of a greater priority, the current priority value is
automatically stored until required.
