18.2.4
Test Data Output (TDO)
The test data output pin (TDO) performs serial output of instructions and data from H-UDI
registers. Transfer is performed in synchronization with TCK. If there is no output, TDO goes to
the high-impedance state.
18.2.5
Test Reset (
TRST

)
The test reset pin (
TRST
) initializes the H-UDI asynchronously. If no signal is input,
TRST
is
fixed at 1 by internal pull-up.

The instruction register (SDIR) is a 16-bit register that can only be read by the CPU. H-UDI
instructions can be transferred to SDIR by serial input from TDI. SDIR can be initialized by the
TRST
signal, but is not initialized by a reset or in standby mode.
SDIR defines 4 valid bits for instruction. If an instruction exceeding 4 bits is input, the last 4 bits
of the serial data will be stored in SDIR.
Operation is not guaranteed if a reserved instruction is set in this register.
Bits 15 to 12—Test Set Bits (TS3–TS0): Table 18.4 shows the instruction configuration.
