General-purpose processor interrupt requests whose input statuses can be confirmed by
bits 15 through 10 of cause register.
Interrupt request that cannot be masked.
Signal initializing the internal status of the processor. Inactivate this signal in synchroniza-
tion with SysClock.
Signal generating a reset exception, without initializing the internal status of the processor.
Inactivate this signal in synchronization with SysClock.
Clock input signal to processor.
This signal sets the endian mode of the system interface.
When setting the endian mode with this signal, specify little endian with the data from the
ModeIn pin that is input at reset.
To set the endian mode with the data from the ModeIn pin, fix this signal to 0.
Successive boot mode data clock output resulting from dividing SysClock by 256.
Input of initialization bit stream.
Signal indicating that the voltage supplied to the V
for 100 ms or more, and that that status is stabilized. When V
