 The response time of the CPU to an interrupt request is a function of the current instruction being executed as well as the number of wait states being asserted. The interrupt vector, {I[7:0], IVECT[7:0]}, is visible on the address bus, ADDR[15:0], when the interrupt
 service routine begins. The response of the CPU to a vectored interrupt on the eZ80F92
 device is explained in Table 12. Interrupt sources are required to be active until the interrupt service routine starts. It is recommended that the Interrupt Page Address Register (I)
-value be changed by the user from its default value of 00h as this address can create conflicts between the nonmaskable interrupt vector, the RST instruction addresses, and the
+value be changed by the user from its default value of 00h as this address can create conflicts between the non-maskable interrupt vector, the RST instruction addresses, and the
 maskable interrupt vectors.
