Register Description

The SIEXmsg register allows an interrupt to be generated on the HPI port. Any write to this register causes the SIEXmsg flag in the HPI Status Port to go high and also causes an interrupt on the HPI_INTR pin. The SIEXmsg flag is automatically cleared when the HPI port reads from this register.

Data (Bits [15:0])

The Data field[15:0] simply must have any value written to it to cause SIExmsg flag in the HPI Status Port to go high.

Register Description

The HPI Mailbox register provides a common mailbox between the CY7C67200 and the external host processor.

If enabled, the HPI Mailbox RX Full interrupt triggers when the external host processor writes to this register. When the CY7C67200 reads this register the HPI Mailbox RX Full interrupt automatically gets cleared.

If enabled, the HPI Mailbox TX Empty interrupt triggers when the external host processor reads from this register. The HPI Mailbox TX Empty interrupt is automatically cleared when the CY7C67200 writes to this register.

In addition, when the CY7C67200 writes to this register, the HPI_INTR signal on the HPI port asserts signaling the external processor that there is data in the mailbox to read. The HPI_INTR signal deasserts when the external host processor reads from this register.

Message (Bits [15:0])

The Message field contains the message that the host processor wrote to the HPI Mailbox register.
