Name
Type Description
Analog Interface
VAREF
Input or Voltage reference – If using the internal voltage reference, this signal will be an output; if
Output using an external voltage reference, this signal will be an input for this reference (see the
FIXED_VAREFSEL and FIXED_VAREFSEL_VAL parameters/generics).
GNDREF
Input Ground reference – If external voltage reference is used, this signal must be connected to the
ground for the reference; otherwise this should be connected to digital ground (logic 0).
AV9, AV8, AV7, AV6, AV5,
AV4, AV3, AV2, AV1, AV0
Input
Analog Voltage Monitor inputs – These signals correspond to the AVx voltage monitor inputs
(AV9 through AV0) of the AB macro.
Note: Unused AVx inputs need to be disabled with the CFG_AVx parameters/generics and
connected to logic 0.
AC9, AC8, AC7, AC6, AC5,
AC4, AC3, AC2, AC1, AC0
Input
Analog Current Monitor inputs – These signals correspond to the ACx current monitor
inputs (AC9 through AC0) of the AB macro.
Note: Unused ACx inputs need to be disabled with the CFG_ACx parameters/generics and
connected to logic 0.
AT9, AT8, AT7, AT6, AT5,
AT4, AT3, AT2, AT1, AT0
Input
Analog Temperature Monitor inputs – These signals correspond to the ATx temperature
monitor inputs (AT9 through AT0) of the AB macro.
Note: Unused ATx inputs need to be disabled with the CFG_ATx parameters/generics and
connected to logic 0.
ATRETURN4, ATRETURN3,
ATRETURN2, ATRETURN1,
ATRETURN0]
Input
Shared Analog Temperature Monitor Returns – These signals correspond to the shared
returns for the temperature monitor inputs (ATRETURN89 through ATRETURN01) of the AB
macro.
DAVOUT9, DAVOUT8,
DAVOUT7, DAVOUT6,
DAVOUT5, DAVOUT4,
DAVOUT3, DAVOUT2,
DAVOUT1, DAVOUT0
Output Digital AV outputs – These signals correspond to the digital AV outputs (DAVOUT9 through
DAVOUT0) of the AB macro. If any of the AVx inputs are configured as digital inputs rather
than analog inputs, their corresponding buffered digital signals are put out on these ports.
DACOUT9, DACOUT8,
DACOUT7, DACOUT6,
DACOUT5, DACOUT4,
DACOUT3, DACOUT2,
DACOUT1, DACOUT0
Output Digital AC outputs – These signals correspond to the digital AC outputs (DACOUT9 through
DACOUT0) of the AB macro. If any of the ACx inputs are configured as digital inputs rather
than analog inputs, their corresponding buffered digital signals are put out on these ports.
DATOUT9, DATOUT8,
DATOUT7, DATOUT6,
DATOUT5, DATOUT4,
DATOUT3, DATOUT2,
DATOUT1, DATOUT0
Output Digital AT outputs – These signals correspond to the digital AT outputs (DATOUT9 through
DATOUT0) of the AB macro. If any of the ATx inputs are configured as digital inputs rather
than analog inputs, their corresponding buffered digital signals are put out on these ports.
DDGDON9, DDGDON8,
DDGDON7, DDGDON6,
DDGDON5, DDGDON4,
DDGDON3, DDGDON2,
DDGDON1, DDGDON0
Input
Direct Digital Gate Driver enables – These signals can control the corresponding GDONx
gate-driver enable inputs (GDON9 through GDON0) of the AB macro if the CFG_GDx
parameters/generics are set appropriately (refer to "Parameter/Generic Descriptions" on
page 6).
AG9, AG8, AG7 AG6, AG5,
AG4, AG3, AG2, AG1, AG0
Output
Analog Gate Driver outputs – These signals correspond to the AGx gate driver outputs (AG9
through AG0) of the AB macro.
Note: If unused, each of these gate driver outputs can be disabled via the CFG_GDx
parameters/generics.
Note: All signals active high (logic 1) unless otherwise noted.
