Bits in 68/69 can be set in one of two ways. All bits in the

registers can be defined separately in configuration and set

to 1 in application tasks. You can also define only the

registers in configuration and “mask”, the variables in

application tasks with BASIC statements AND or OR.

4.49.2 Registers 104/105: Interrupt Source

Registers 104/105 are the interrupt source registers and

correspond to registers 72/73 in the same manner as do

registers 68/69. A user application program should read

registers 104/105 to see which bit(s) were set after an

interrupt occurs, i.e. after the EVENT has been set. The

source of the interrupt is the corresponding bit(s) in registers

72/73. For example, to continue the example above in

4.49.1, if bit 5 in register 105 is set, the interrupt was caused
