Section 16 Synchronous Serial Communication Unit (SSU)
16.5
The SSU interrupt requests are an overrun error, a conflict error, a receive data register full,
transmit data register empty, and a transmit end interrupts. Of these interrupt sources, a receive
data register full, and a transmit data register empty can activate the DMAC for data transfer.
Since both an overrun error and a conflict error interrupts are allocated to the SSERI vector
address, and both a transmit data register empty and a transmit end interrupts are allocated to the
SSTXI vector address, the interrupt source should be decided by their flags. Table 16.8 lists the
interrupt sources.
When an interrupt condition shown in table 16.8 is satisfied, an interrupt is requested. Clear the
interrupt source by CPU or DMAC data transfer.
