ATF1504ASV(L)
1409J–PLD–6/05
JTAG-BST/ISP
Overview
The JTAG boundary-scan testing is controlled by the Test Access Port (TAP) controller
in the ATF1504ASV(L). The boundary-scan technique involves the inclusion of a shift-
register stage (contained in a boundary-scan cell) adjacent to each component so that
signals at component boundaries can be controlled and observed using scan testing
principles. Each input pin and I/O pin has its own boundary-scan cell (BSC) in order to
support boundary-scan testing. The ATF1504ASV(L) does not currently include a Test
Reset (TRST) input pin because the TAP controller is automatically reset at power-up.
The five JTAG modes supported include: SAMPLE/PRELOAD, EXTEST, BYPASS,
IDCODE and HIGHZ. The ATF1504ASV(L)’s ISP can be fully described using JTAG’s
BSDL as described in IEEE Standard 1149.1b. This allows ATF1504ASV(L) program-
ming to be described and implemented using any one of the third-party development
tools supporting this standard.
The ATF1504ASV(L) has the option of using four JTAG-standard I/O pins for boundary-
scan testing (BST) and in-system programming (ISP) purposes. The ATF1504ASV(L) is
programmable through the four JTAG pins using the IEEE standard JTAG programming
protocol established by IEEE Standard 1149.1 using 5V TTL-level programming signals
from the ISP interface for in-system programming. The JTAG feature is a programmable
option. If JTAG (BST or ISP) is not needed, then the four JTAG control pins are avail-
able as I/O pins.
JTAG Boundary-scan
Cell (BSC) Testing
The ATF1504ASV(L) contains up to 68 I/O pins and four input pins, depending on the
device type and package type selected. Each input pin and I/O pin has its own bound-
ary-scan cell (BSC) in order to support boundary-scan testing as described in detail by
IEEE Standard 1149.1. A typical BSC consists of three capture registers or scan regis-
ters and up to two update registers. There are two types of BSCs, one for input or I/O
pin, and one for the macrocells. The BSCs in the device are chained together through
the capture registers. Input to the capture register chain is fed in from the TDI pin while
the output is directed to the TDO pin. Capture registers are used to capture active
device data signals, to shift data in and out of the device and to load data into the update
registers. Control signals are generated internally by the JTAG TAP controller. The BSC
configuration for the input and I/O pins and macrocells are shown below.

Pins)
Note:
The ATF1504ASV(L) has pull-up option on TMS and TDI pins. This feature is selected as
a design option.
