5.2
This mode includes the Mailbox Protocol and DMA Protocol. The Mailbox Protocol allows asynchronous exchange of data
between an external Processor (i.e. DSP or Microprocessors) and the SL11R, via the bidirectional data port SD15-SD0
(GPIO15-0). The DMA Protocol allows the large data blocks to be transferred to or from SL11R memory devices via the 8/16-bit
DMA port.
The SL11R has four built-in PWM output channels available in the 8/16-bit DMA mode. Each channel provides a programmable
timing generator sequence which can be used to interface to various line CCD, CIS, CMOS image sensors or can be used for
other types of applications (see Programmable Pulse/PWM Interface for more detail of controlling these PWM functions).
Note: Any other unused IO pins can be used as the GPIO pins under control of the General Purpose IO mode (GPIO).
