• Manufacturer Part Number: cs5954am
• Description: Usb Controller For Nand Flash
• Manufacturer: Cypress Semiconductor Corporation.

Table 4-4. Software Interrupt Table
4.11.3
This register defines the polarity of the GPIO interrupt on IRQ1 (GPIO25) and IRQ0 (GPIO24). The GPIO bit on the Interrupt
Enable Register must be set in order for this register to operate.
4.11.4
The CS5954AM allocates addresses from 0x0040 to 0x00FE for software interrupts. The software interrupt vectors are shown in
Table 4-4.
Document #: 38-08025 Rev. **
Notes:
14. The interrupts can be enabled for “Suspend mode” by the Power-down Register or enabled for interrupts by the Interrupt Enable Register.
15. These software vectors are reserved for the internal CS5954AM-BIOS. The user should not overwrite these functions.
16. These vectors are used as the data pointers. The user should not execute code (i.e. JMP or INT) to these vectors.
