(6) Interrupt control registers
Interrupt control register V1
Interrupt enable bits of external 0, timer 1 and timer 2 are
assigned to register V1. Set the contents of this register through
register A with the TV1A instruction. The TAV1 instruction can
be used to transfer the contents of register V1 to register A.
Interrupt control register V2
The timer 3 interrupt enable bit are assigned to register V2. Set
the contents of this register through register A with the TV2A
instruction. The TAV2 instruction can be used to transfer the
contents of register V2 to register A.
Note 1.“R” represents read enabled, and “W” represents write enabled.
(7) Interrupt sequence
Interrupts occur only when the respective INTE flag, interrupt
enable bits (V10, V12, V13, V30), and interrupt request flag are
set to “1.” The interrupt occurs two or three cycles after the cycle
where all the above three conditions are satisfied.
The interrupt occurs after three machine cycles if instructions
other than one-cycle instruction are executed when the
conditions are satisfied (Refer to Figure 27).
