Global Digital Interconnect (GDI)
14.2
Register Definitions
The following registers are associated with the Global Digital Interconnect and are listed in address order. Each register
description has an associated register table showing the bit structure for that register. For a complete table of GDI registers,
refer to the
“Summary Table of the Digital Registers” on page 162
.
14.2.1
GDI_x_IN Registers
The Global Digital Interconnect Odd and Even Input Regis-
ters (GDI_x_IN) are used to configure a global input to drive
a global output.
The PSoC device has a configurable Global Digital Intercon-
nect (GDI). Note that the GDI_x_IN and GDI_x_OU regis-
ters should never have the same bits connected. This
results in multiple drivers of one bus.
Bits 7 to 0: GIxNOUTx.
Using the configuration bits in the
GDI_x_IN registers, a global input net may be configured to
drive its corresponding global output net. For example,
The configurability of the GDI does not allow odd and even
nets or nets with different indexes to be connected. The fol-
lowing are examples of connections that are not possible in
the PSoC devices.
There are a total of 16 bits that control the ability of global
inputs to drive global outputs. These bits are in the
GDI_x_IN registers.
enumerates the meaning of
each bit position in either of the GDI_O_IN or GDI_E_IN
registers.
