(6) Interrupt control register
G
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.
