Microchip dsPIC30F Series Reference Manual Chapter 28 Interrupts Part 2
Chapter 28 of the Microchip dsPIC30F Series Reference Manual provides a detailed overview of the device's interrupt controller. It explains how external peripheral interrupts are simplified into a single request signal for the CPU and describes the architecture supporting up to 62 vectors in the Interrupt Vector Table (IVT). The chapter also covers the Alternate Interrupt Vector Table (AIVT) used for debugging and switching between applications. This manual is written in Chinese.

Questions answered in these manuals
What is the starting address of the Interrupt Vector Table (IVT)?
The IVT is located in program memory starting at address 0x000004.
From: Microchip dsPIC30F Series Reference Manual Chapter 28 Interrupts Part 2
How many interrupt vectors are included in the IVT?
The Interrupt Vector Table contains 62 vectors, consisting of 8 non-maskable trap vectors and up to 54 interrupt sources.

What are the four pins used by the SPI1 module?
The four pins are SDI1 (Serial Data Input), SDO1 (Serial Data Output), SCK1 (Shift Clock Input or Output), and SS1 (Low-Active Slave Select or Frame Sync I/O pulse).
From: Microchip dsPIC30F Series Reference Manual Chapter 35 SPI
Can the SPI1 module operate in 2 or 3 pin modes?
Yes, it can be configured to use 2, 3, or 4 pins. In 3-pin mode, SS1 is not used, and in 2-pin mode, SDO1 and SS1 are not used.

What are the advantages of BLDC motors?
BLDC motors reduce energy consumption and maintenance costs, and they eliminate mechanical commutators and carbon brushes, which enhances mechanical reliability and allows operation in harsh environments.
From: Microchip dsPIC30F BLDC Motor Control Application Guide
What hardware platforms are mentioned for BLDC motor control?
The document mentions the PICDEM™ MC LV development board for low voltage applications and the dsPICDEM™ MC1 development board for a wider range of applications including high voltage.
