(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.
