Intel 64 and IA-32 Architectures

6.8.1
Masking Maskable Hardware Interrupts
The fact that the group of maskable hardware interrupts includes the reserved inter-
rupt and exception vectors 0 through 32 can potentially cause confusion. Architectur-
ally, when the IF flag is set, an interrupt for any of the vectors from 0 through 32 can
be delivered to the processor through the INTR pin and any of the vectors from 16
through 32 can be delivered through the local APIC.
----------------------------------------------------------------------------------------------------
I just copied some lines of Intel manual in the above.
It says: "...reserved interrupt and exception vectors 0 through 32..."
Reserved and exception vectors are from 0 to 31!! not 32.
Vector number 32, is a user defined vector as far as I know.
Please let me know if there is a mistake as I said.

You are correct that this is a somewhat imprecise use of the word "through" and differs from its use earlier in the section. Reserved vectors are 0 - 31. User-defined vectors range from 32 - 255.
