RS_INT1 is interrupt of Channel C and D
RS_INT2 is interrupt of Channel E and F
RS_INT3 is interrupt of Channel G and H
RS_INT4 is interrupt of Channel I and J
RS_INT5 is the output of Z85C230, Channel K and L
JTAG_INT JTAG interrupt, connected to pin 19
of the SCANPCS100F
CAN_INT CAN interrupt, connected to pin 16
of the SJA1000
TMP_INT High Temperature interrupt
LAN_INT Ethernet Interrupt, pin 6 of Am7990
F_INT Fast Ethernet Interrupt, pin 1 of the DEC 21140A
LINK_INT Fast Ethernet Link Interrupt, pin 38 of the DP83840A
The routed distribution of source interrupts and their location in the corresponding interrupt regis-
ter are as follows:
Interrupt Level Location
INT_0 INT_1 INT_2 INT_3 INT_4 in Reg.
IRQ1 IRQ4 IRQ6 0 IRQ7 D0
TMP_INT IRQ3 IRQ5 0 F_INT D1
res TIM_INT1 IRQ2 0 0 LINK_INT D2
0 0 0 0 res FDDI D3
0 0 0 0 res FDDI D4
0 0 0 0 res FDDI D5
0 0 0 0 res FDDI D6
RS_INT 0 0 res TIM_INT0 LAN_INT D7
Notes:
RS_INT is the ored sum of RS_INT0,...,RS_INT5, JTAG_INT and CAN_INT
Bits 2 to 6 of INT_4 are reserved for FDDI source interrupts.
Bits 2 of INT_0 and 7 of INT_3 are reserved for DP8571A
Timer source interrupts.
Bit 0 of INT_4 is a VME–bus interrupt .7
Bit 7 of INT_4 is a 10Mb/s Am7990 Ethernet Controller interrupt.
