INTERRUPTS STRUCTURE
Interrupt Option Register IOR
Bit 6 of register C8h is used to select negative edge (B6 = 0) or low level (B6 = 1) I1 interrupt sensitivity.
Bit 5 of register C8h is used to select negative edge (B5 = 0) or positive edge (B5 = 1) I2 interrupt
sensitivity.
Bit 4 of register C8h is used to disable (B4=0) all maskable interrupts.
Register C8h is cleared during reset.
There are no read and single bit instructions possible.
See also interrupt circuit diagram (Fig. 11).
Test mode pin TEST has to be low for normal operation.
Interrupts
Non maskable interrupt input IO is connected to the power bridge flags (start address FFCH).
I1 is connected to PORT A
(start address FF6H).
I2 is connected to Bus Interface and CAN Controller
(start address FF4H).
I3 is connected to Contact Monitor
(start address FF2H).
I4 is connected to TIMER1
(start address FF0H).
The interrupt characteristics of I/O port A can be programmed in four different modes.
Interrupt polarity is selected by bit PAES of register BPCR, interrupt sensitivity is controlled by bit 6 of
register IOR (see following table 3).
