UPADDREN
(BU-6174X,
BU-6184X only)
UPADDREN
For BU-61864/61865FX/GX, this pin signal is +5V-RAM and
MUST be connected to +5V.
For the 61860BX, this signal must be connected to logic "1".
For BU-6174X and 6184X, this signal is used to control the func-
tion of the upper 4 address inputs (A15-A12). For these versions of
Enhanced Mini-ACE, if UPADDREN is connected to logic "1", then
these four signals operate as address lines A15-A12.
For BU-6184X/6174X, if UPADDREN is connected to logic "0",
then A15 and A14 function as CLK_SEL_1 and CLK_SEL_0
respectively; A13 MUST be connected to Vcc-LOGIC (+5V or
+3.3V); and A12 functions as RTBOOT.

-
MCRST (O)
For RT mode MCRST will be asserted low for two clock cycles fol-
lowing receipt of a Reset remote terminal mode command.
-
A13
INT (O)
Interrupt Request output. If the LEVEL/PULSE interrupt bit (bit 3)
of Configuration Register #2 is logic "0", a negative pulse of
approximately 500ns in width is output on INT to signal an inter-
rupt request.
If LEVEL/PULSE is high, a low level interrupt request output will
be asserted on INT. The level interrupt will be cleared (high) after
either: (1) The processor writes a value of logic "1" to INTERRUPT
RESET, bit 2 of the Start/Reset Register; or (2) If bit 4 of
Configuration Register #2, INTERRUPT STATUS AUTO-CLEAR is
logic "1", then it will only be necessary to read the Interrupt Status
Register (#1 and/or #2) that is requesting an interrupt that has
been enabled by the corresponding Interrupt Mask Register.
However, for the case where both Interrupt Status Register #1 and
Interrupt Status Register #2 have bits set reflecting interrupt
events, it will be necessary to read both interrupt status registers
in order to clear INT.

INCMD (O)
For BC, RT, or Selective Message Monitor modes, INCMD is
asserted low whenever a message is being processed by the
Enhanced Mini-ACE. In Word Monitor mode, INCMD will be assert-
ed low for as long as the monitor is online.
-
M1
INCMD (O) /
MCRST (O)
-
In-command or Mode Code Reset. The function of this pin is con-
trolled by bit 0 of Configuration Register #7, MODE CODE
RESET/INCMD SELECT.
If this register bit is logic "0" (default), INCMD will be active on this
pin. For BC, RT, or Selective Message Monitor modes, INCMD is
asserted low whenever a message is being processed by the
Enhanced Mini-ACE. In Word Monitor mode, INCMD will be assert-
ed low for as long as the monitor is online.
For RT mode, if MODE CODE RESET/INCMD SELECT is pro-
grammed to logic "1", MCRST will be active. In this case, MCRST
will be asserted low for two clock cycles following receipt of a
Reset remote terminal mode command.
In BC or Monitor modes, if MODE CODE RESET/INCMD SELECT
is logic "1", this signal is inoperative; i.e., in this case, it will always
output a value of logic "1".
