Macro Definition Documentation

AICA_CMD_MAX_SIZE

#define AICA_CMD_MAX_SIZE   256

Maximum command size – 256 dwords.

AICA_CMDSTR_CHANNEL

#define AICA_CMDSTR_CHANNEL	(		T,
			CMDR,
			CHANR )

Value:

    uint8   T[sizeof(aica_cmd_t) + sizeof(aica_channel_t)]; \
    aica_cmd_t  * CMDR = (aica_cmd_t *)T; \
    aica_channel_t  * CHANR = (aica_channel_t *)(CMDR->cmd_data);

Macro for declaring an aica channel command.

Declare an aica_cmd_t big enough to hold an aica_channel_t using temp name T, aica_cmd_t name CMDR, and aica_channel_t name CHANR

Parameters

T	Buffer name
CMDR	aica_cmd_t pointer name
CHANR	aica_channel_t pointer name

AICA_CMDSTR_CHANNEL_SIZE

#define AICA_CMDSTR_CHANNEL_SIZE   ((sizeof(aica_cmd_t) + sizeof(aica_channel_t))/4)

Size of an AICA channel command in words.
