Reset
An H-UDI reset is executed by inputting an H-UDI reset assert command in SDIR. An H-UDI
reset is of the same kind as a power-on reset. An H-UDI reset is released by inputting an H-UDI
reset negate command. The required time between the H-UDI reset assert command and H-UDI
reset negate command is the same as time for keeping the
RESETP
pin low to apply a power-on
reset.

Interrupt
The H-UDI interrupt function generates an interrupt by setting a command from the H-UDI in the
SDIR. An H-UDI interrupt is a general exception/interrupt operation, resulting in a branch to an
address based on the VBR value plus offset, and with return by the RTE instruction. This interrupt
request has a fixed priority level of 15.
H-UDI interrupts are accepted in sleep mode.
