Description
When Not
in Use
TCK Clock
Input
Functions as the serial clock input pin stipulated in
the JTAG standard. Data input to the H-UDI via the
TDI pin or data Output via the TDO pin is performed
in synchronization with this signal.

TMS Mode
Input
Mode Select Input
Changing this signal in synchronization with the TCK
signal determines the significance of data input via
the TDI pin. Its protocol conforms to the JTAG
standard (IEEE standard 1149.1).

Reset Input
H-UDI Reset Input
This signal is received asynchronously with a TCK
signal. Asserting this signal resets the JTAG interface
circuit. When a power is supplied, the
TRST
pin
should be asserted for a given period regardless of
whether or not the JTAG function is used, which
differs from the JTAG standard.

Selects the operation mode of this LSI, whether
emulation support mode (Low level) or LSI operation
mode (High level).

Notes: 1. This pin is pulled up in this LSI. When using interrupts or resets via the H-UDI or
emulator, the use of external pull-up resistors will not cause any problem.
2. When using interrupts or resets via the H-UDI or emulator, the
TRST
pin should be
designed so that it can be controlled independently and can be controlled to retain low
level while the
PRESET
pin is asserted at a power-on reset.
