AS91L1006BU
SELF_TEST Register
The AS91L1006BU device supports a
single output pin that can be controlled via the
IEEE1149.1 interface. When the instruction is
loaded into the AS91L1006BU instruction register,
a single bit data register is connected which is
always reset to logic zero when the TAP state
machine enters Capture-DR. This will cause the
SELF_TEST pin to pulse low for one cycle of TCK,
during the Update-DR phase. This low going pulse
can be used to initiate self-tests on PCB’s in a rack
via the JTAG interface.
LSP_ASYNC_RST Register
The AS91L1006BU device supports async
reset tests on the devices connected to the LSPs.
The standard method of performing these tests by
utilizing the primary TRST pin cannot be used as it
will cause the AS91L1006BU to deselect and its
internal registers to be reset. In order to enable
async reset tests on LSPs, the test tool should
instruct the device to toggle the LSP reset pins
while maintaining the set up information in the
AS91L1006BU. When the instruction is loaded
into the AS91L1006BU instruction register, a
single bit data register is connected as the data
register which is always reset to logic zero when
the TAP state machine enters Capture-DR. This
will cause the LSP TRST pins to pulse low for one
TCK cycle, during the Update-DR phase.
AUTOWR Register
This is a 6-bit register that controls the pass-
through of the JTAG Technologies AutoWR
signal to any LSP. The register is reset to all
zeros when entering the Test-Logic-Reset state.
Note: The MCGR is reset to 00 upon receiving TRST or the entering of the
Test-Logic-Reset state
