(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.
