SYNC : CPU operation code fetch cycle
(This is an internal signal that cannot be observed from the external unit.)
BL, BH: Vector address of each interrupt
AL, AH: Jump destination address of each interrupt
SPS
: “0016” or “0116”
([SPS] is a page selected by the stack page selection bit of CPU mode register.)
T1
(1) The interrupt request bit for an interrupt request generated during period 1 is set to “1” at timing point IR1.
(2) The interrupt request bit for an interrupt request generated during period 2 is set to “1” at timing point IR1 or IR2.
requests are generated during the period 2, each request bit may be set to “1” at timing point IR1 or IR2
separately.
T1 T2 T3 : Interrupt acceptance timing points
IR1 IR2 : Timings points at which the interrupt request bit is set to “1”.
Note : Period 2 indicates the last
φ cycle during one instruction cycle.
