CHAPTER 3 INTERRUPT
At the end caused by an end request from the peripheral function (I/O)
2
If data transfer by EI OS is aborted due to an end request from the peripheral function (I/O) (ICR S1, ICR
2
S0 = 11), the hardware interrupt is activated without performing data transfer. The EI OS processing time
is calculated using the expression below. Z in the expression represents the interrupt handling time
compensation value (see Table 3.6-4).
2 OS processing time for aborted = 36 + 6 × Z machine cycles
EI
Reference:
One machine cycle is equal to one clock cycle of the machine clock (φ).
