I/O Lines Description
The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
Before using the SSC receiver, the PIO controller must be configured to dedicate the SSC
receiver I/O lines to the SSC peripheral mode.
Before using the SSC transmitter, the PIO controller must be configured to dedicate the SSC
transmitter I/O lines to the SSC peripheral mode.
The SSC clock is generated by the power manager. Before using the SSC, the programmer
must ensure that the SSC clock is enabled in the power manager.
In the SSC description, Master Clock (CLK_SSC) is the bus clock of the peripheral bus to which
the SSC is connected.
The SSC interface has an interrupt line connected to the interrupt controller. Handling interrupts
requires programming the interrupt controller before configuring the SSC.
All SSC interrupts can be enabled/disabled configuring the SSC Interrupt mask register. Each
pending and unmasked SSC interrupt will assert the SSC interrupt line. The SSC interrupt ser-
vice routine can get the interrupt origin by reading the SSC interrupt status register.
This chapter contains the functional description of the following: SSC Functional Block, Clock
Management, Data format, Start, Transmitter, Receiver and Frame Sync.
The receiver and transmitter operate separately. However, they can work synchronously by pro-
gramming the receiver to use the transmit clock and/or to start a data transfer when transmission
starts. Alternatively, this can be done by programming the transmitter to use the receive clock
and/or to start a data transfer when reception starts. The transmitter and the receiver can be pro-
grammed to operate with the clock signals provided on either the TX_CLOCK or RX_CLOCK
pins. This allows the SSC to support many slave-mode data transfers. The maximum clock
speed allowed on the TX_CLOCK and RX_CLOCK pins is the master clock divided by 2.
