21.1
21.1.1
The high-performance user debug interface (H-UDI) is a serial input/output interface supporting a
subset of the JTAG, IEEE 1149.1, IEEE Standard Test Access Port and Boundary-Scan
Architecture. The SH7750R's H-UDI supports boundary-scan, but is used for emulator connection
as well. The functions of this interface should not be used when using an emulator. Refer to the
emulator manual for the method of connecting the emulator. The H-UDI uses six pins (TCK,
TMS, TDI, TDO, TRST, and ASEBRK/BRKACK). The pin functions and serial transfer protocol
conform to the JTAG specifications.
21.1.2
Figure 21.1 shows a block diagram of the H-UDI. The TAP (test access port) controller and
control registers are reset independently of the chip reset pin by driving the TRST pin low or
setting TMS to 1 and applying TCK for at least five clock cycles. The other circuits are reset and
initialized in an ordinary reset. The H-UDI circuit has four internal registers: SDBPR, SDIR,
SDDRH, and SDDRL (these last two together designated SDDR). The SDBPR register supports
the JTAG bypass mode, SDIR is the command register, and SDDR is the data register. SDIR can
be accessed directly from the TDI and TDO pins.
