30. User Debugging Interface (H-UDI)
Notes: 1. This pin is pulled up in the chip. In designing the board that can connect an emulator, or
The TCK clock or the CPG of this LSI should be set so that the frequency of the TCK clock is less
than that of the peripheral clock of this LSI. For details of the setting of the CPG, see section 15,
Clock Pulse Generator (CPG).

3. This pin should be connected to ground, or connected to the same signal as the
using interrupts or resets through the H-UDI, there is no problem with putting the pull-up
resistor outside this LSI.
through the H-UDI, the TRST pin should be set so that it can be held low while the
PRESET signal is low after power is turned on and the TRST pin can be controlled
independently.
PRESET, or a pin which operates in the same way as the PRESET pin. When this pin
is connected to ground, the following problem occurs. Since the TRST pin is pulled up
within this LSI, weak current runs when the pin is connected to ground outside the LSI.
The current depends on a resistance of the pull-up for the port pin. Although this current
does not affect the operation of this LSI, it consumes unnecessary power.
