TS2
I
Bus Cycle Status:
Used by Am186 family
of microcontrollers as a logical memory
or I/O indicator.
45
PARINT
O
Printer Port Interrupt:
Dedicated
parallel port interrupt signal.
46
–
–
Pin is blank.
47
SERINT1
O
Serial Port 1 Interrupt:
Dedicated serial
port 1 interrupt signal.
48
MAIN_IRQ
O
Main Interrupt Line:
A shared interrupt
line. MAIN_IRQ is asserted if any of the
five interrupts on the TIP board are
asserted.
49
SERINT0
O
Serial Port 0 Interrupt:
Dedicated serial
port 0 interrupt signal.
50
HRESET
O
Host Reset:
Toggled by the TIP board
reset button, which then indicates to the
host microcontroller to perform a system-
wide hardware reset.
51
IOCHRDY
O
I/O Channel Ready:
Indication by the
Ethernet controller that valid data exists
on the data bus for reads and that data has
been latched for writes.
52
TRESET
I
TIP Reset:
Generated by the host
microcontroller when performing a
hardware reset. TRESET affects the TIP
board’s Ethernet controller, and parallel
and serial ports.
