Notes: 1. This pin is pulled-up within the LSI after a power-on reset (initial state). Set the IPUP bit
in BCR (MCU) to 1 to switch pulling-up of the RDY pin off.
Pulling-up of the BREQ pin is also off when the IPUP bit is 1. So if the BREQ pin is in
use, use a pull-up resistance on the board to pull the BREQ pin up.
2. When designing a board for use with an emulator, follow the directions for the emulator.
3. When not using emulator, the pin should be fixed to ground or connected to another pin
which operates in the same manner as PRESET. However, since the TRST pin is
pulled up within this LSI, a weak current flows when the pin is externally connected to
ground pin. The value of the current is determined by a resistance of the pull-up MOS
for the TRST pin. Although this current does not affect the operation of this LSI, it
consumes power unnecessarily.
4. Treatment of pins if unused refers to the pin state after a power-on reset.
