Detailed Description

MC6850-compatible ODIE communication port.

This class represents an ODIE communication port set to MS6850-compatible mode. This is the only recommended mode for the secondary port, and its command channel is used to interface the firmware.

Constructor & Destructor Documentation

SS6850Port()

Soundscape::SS6850Port::SS6850Port	(	std::uint16_t	base,
		bool	with_reset )

The constructor writes a control value that takes the port out of reset, after optionally setting it to reset first.

Parameters

base	I/O base address of the port. 0x332 for the secondary port of a Soundscape in default config.
with_reset	If set, reset the port (not the firmware).

Exceptions

HWMissingException

There obviously is no Sounscape port in MC6850 mode at the given address.
