, External Conditional Jump (JX)
[AK7712A-VT]
The timing of external conditional jump is shown as follows. This command inputs the jump condition from outside of
LSI to 8-bit conditional jump register. When one of "1" of each bits of it and external conditional register is
coincident, the jump is executed. If it is satisfied, the address of jump destination is set. Then one machine cycle of
NOP is inserted similar to jump. And if the condition is not satisfied, NOP is not inserted, next address command is
executed.
The data is set to conditional jump register at rising edge of LRCK in motion or reset.
, Subroutine Call (CL)
The timing of subroutine call is shown as follows. This command stacks next address before address of call
destination, NOP is inserted. The preparation for pushing the stacked address is done on return address, and stack
address is executed after return address. Then NOP is not inserted.
