(1) Interrupt control register V1
The timer 1 interrupt enable bit is assigned to bit 2, and the timer 2 interrupt enable bit is assigned
to bit 3.
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.
Table 2.3.1 shows the interrupt control register V1.
