Section 20 Synchronous Serial Communication Unit (SSU)
20.5
The SSU interrupt requests are an overrun error, a conflict error, a receive data full, transmit data
empty, and a transmit end interrupts.
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 20.7 lists the
interrupt sources.
When an interrupt condition shown in table 20.7 is satisfied, an interrupt is requested. Clear the
interrupt source by the CPU.
