JTAG registers
Command registers
Command register is constituted by 3 bits register
which keeps command code, and is set in the IR
path sequence. Data register, which is selected in
the f ollowing path sequence, is determined by the
command which is set into the command register.
Initial v alue in test reset is IDCODE command.
Until the command code is set f rom external,
IDCODE register is kept selecting as the data
register.
M66290A supports three commands (EXTEST,
SAMPLE/PRELOAD, and BYPASS) which are
established as essential by IEEE 1149.1 and the
dev ice recognize register access command
(IDCODE).
Below are the commands and the related code.
EXTEST (Command code : b'000)
Executes outside circuit connection test and on
board connection test. Reads the TDI input into the
"Boundary Scan Register" and outputs the contents
of "Boundary Scan Register" f rom TDO.
IDCODE (Command code : b'001)
Selects the "IDCODE Register" and outputs the
dev ice and company discrimination data f rom
TDO.
SAMPLE/PRELOAD (Command code : b'010)
Samples the circuit status in operation and outputs
it f rom TDO, and at the same time, inputs the data
f rom TDI which will be use in the next boundary
scan test and set into the "Boundary Scan Register"
prev iously .
BYPASS (Command code : b'111)
Selects the "BYPASS Register" and executes the
ref er and the set of the data.
Don't set the command code except f or abov e.
Data registers
(1) Boundary scan register (JTAGBSR)
This is f or boundary scan test and is assigned to each
terminal of M66290A which is related to JTAG.
Boundary scan register is connected between TDI and
TDO terminal, and is selected when "EXTEST Command"
is ordered. This register captures the status of input
terminal or the output v alue f rom internal logic circuit in
the state of C apture-DR. In the state of Shif t-DR, input
the data f or boundary scan test parallely outputting the
sampled v alue. And set terminal f unction (IN/OUT of
bidirectional terminal or direction of 3-state output) and
output v alue.
As to the JTAG related terminal and the structure of
boundary scan, ref er to BSDL specially.
(2) BYPASS register (JTAGBPR)
BYPASS register is one bit register to by pass the boundary
scan path when M66290A is not the object in boundary scan
test. BYPASS register is connected between TDI and TDO
terminal, and is selected when "BTPASS command" is
ordered. In the state of C apture-DR, "0" is loaded.
(4) IDCODE register (JTAGIDR)
IDCODE register is a register of 32bits to discriminate the
dev ice and the company , and keeps inf ormation as f ollows.
IDCODE register is connected between TDI and TDO
terminal,
and is selected when "IDCODE Command" is ordered.
IDCODE data is loaded in Capture-DR state and is output
f rom TDO in Shif t-DR state.
