OFFSET:0x02c4
NAME
SYNCHRO_CPU2iSoP
The following describes the procedures of sequencer complete interrupt request.
(1) Sequencer completion request (change the bit of the corresponding sequencer of START_MODE0 within
SCU_REG from "1" to "0")
(2) Check that Sleep setting is released. If not released, set HPADC0_ACCESS_INHIBIT_REQ within
SCU_REG to "1" (SLEEP release and prohibition)
(3) Clear the SCU interrupt factor
(4) Disable the iSoP3 IRQ interrupt mask
(5) Set the complete/suspend request sequencer number to the SYNCHRO_CPU2iSoP
(6) Set LPADC_ACCESS_INHIBIT_REQ within the SCU_REG to "1" (complete interrupt request)
(7) Wait for the interrupt
(8) Within the following interrupt context:
(i) Set LPADC_ACCESS_INHIBIT_REQ to "0" (release the complete interrupt request)
(ii) Set the iSoP3 IRQ interrupt mask
(iii) Clear the interrupt factor
(9)When SLEEP needs to be enabled, set HPADC0_ACCESS_INHIBIT_REQ to "0" (SLEEP enable)
(10) End of procedure
The following describes the procedures of sequencer suspend interrupts.
