(6) Interrupt control registers

• Interrupt control register V1

Interrupt enable bits of external 0, external 1, 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

Interrupt enable bits of timer 3, timer 4, A-D and serial I/O are as-

signed 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.
