UPADDREN (I)
Logic "1"
C12
This signal is used to control the function of the upper 4 address
inputs (A15-A12). If UPADDREN is connected to logic "1", then these
four signals operate as address lines A15-A12. If UPADDREN is con-
nected to logic "0", then A15 and A14 function as CLK_SEL_1 and
CLK_SEL_0 respectively; A13 MUST be connected to LOGIC "1"; and
A12 functions as RTBOOT.

BALL
F7
SLEEPIN (I)
-
This signal is used to control the transceiver sleep (power-down) cir-
cuitry. If SLEEPIN is connected to logic "0", the transceivers are fully
powered and operate normally. If SLEEPIN is connected to logic "1",
the transceivers are in sleep mode (dormant, low-power mode) of
operation and are NOT operational.
R4
INCMD (O)
H16
For BC, RT, or Selective Message Monitor modes, INCMD is asserted
low whenever a message is being processed by the Micro-ACE-TE. In
Word Monitor mode, INCMD will be asserted low for as long as the
monitor is online.
P17
MCRST (O)
B13
For RT mode MCRST will be asserted low for two clock cycles follow-
ing receipt of a Reset remote terminal mode command.
D11
RSTBITEN (I)
M18
If this input is set to logic "1", the Built-In-Self-Test (BIST) will be
enabled after hardware reset (for example, following power-up). A logic
"0" input disables both the power-up and user-initiated automatic BIST.
L14
INT (O)
D17
Interrupt Request output. If the LEVEL/PULSE interrupt bit (bit 3) of
Configuration Register #2 is logic "0", a negative pulse of approxi-
mately 500 ns in width is output on INT to signal an interrupt 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 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.
D18
CLOCK_IN (I)
M9
20 MHz, 16 MHz, 12 MHz, or 10 MHz clock input.
T10
MSTCLR (I)
B11
Master Clear. Negative true Reset input, normally asserted low follow-
ing power turn-on.
R18
TAG_CLK (I)
D18
Time Tag Clock. External clock that may be used to increment the
Time Tag Register. This option is selected by setting Bits 7, 8 and 9 of
Configuration Register # 2 to Logic "1".
F14
TX_INH_A (I)
TX_INH_B (I)
A14
Transmitter inhibit inputs for Channel A and Channel B, MIL-STD-
1553 transmitters. For normal operation, these inputs should be con-
nected to logic "0". To force a shutdown of Channel A and/or Channel
B, a value of logic "1" should be applied to the respective TX_INH
input.
