Register of interrupts. Line of separable interrupts is set via the byte port with
the address BA + Dh . The port is available when recording, has the following format:
Table 3-9: Register of interrupts
Address D7 D6 D5 D4 D3 D2 D1 D0
BA + Dh - - GRP1 GRP0 INTF LN2 LN1 LN0
LN[2:0] Code of interrupt line
(LN[2:0] = 3…7). Connection of interrupt line is carried
out by writing of the code corresponding to the number of line IRQ3…IRQ7.
INTF Permit of interrupt from the frequency meter. During setting the bit the
interrupts are permitted from the frequency meter.
NOTE:
INTERRUPT FROM FREQUENCY METER - BIT INVERSION ST_RDY.
GRP1,0 Permission of interrupts from input groups (byte-wise). When setting the bits it is
permitted, accordingly, to perform interrupts from input groups IN[15:8],
IN[7:0].

Permission of interrupts from input groups (byte-wise). When setting the bits it
