7.5.1 Hardware Configuration
To configure the hardware for working with the interrupt mechanism, connect the IRQ# ball to the
host interrupt input.
Note: A nominal 10 KΩ pull-up resistor should be connected to this ball.
7.5.2
Configuring the software to support the IRQ# interrupt is performed in two stages.
Stage 1
Configure the software so that when the system is initialized, the following steps occur:
1.
2. The host interrupt is configured to the selected input type, either edge or level-triggered.
3.
4. The interrupt service routine to the host interrupt is connected and enabled.
Stage 2
Configure the software so that for every long flash I/O operation, the following steps occur:
1.
2.
3.
4. The OS either returns control immediately to the TrueFFS driver, or waits for the appropriate

Note: Refer to Section 5.9 for further information on the value to write to this register.
The handshake mechanism between the interrupt handler and the OS is initialized.
The correct value is written to the Interrupt Control register to enable the IRQ# interrupt.
Note: Refer to Section 5 for further information on the value to write to this register.
The flash I/O operation starts.
Control is returned to the OS to continue other tasks. When the IRQ# is received, other
interrupts are disabled and the OS is flagged.
