void SND_StartTimer( u32 chBitMask, u32 capBitMask, u32 alarmBitMask, u32 flags );
chBitMask |
The channel bit mask. It specifies which channels to control. |
capBitMask |
The capture bit mask. It specifies which captures to control. |
alarmBitMask |
The alarm bit mask. It specifies which Sound alarms to control. |
flags |
Option flags. At the current time the flags are not used, so 0 is entered here. |
Starts timers.
By specifying numerous channels, captures and alarms all at once, you can start them all with the same timing. The order is: channel -> capture -> alarm. The individual channels, captures and alarms must have already been set up using the SND_SetupChannelPcm
, SND_SetupCapture
and SND_SetupAlarm
functions.
The channel bit mask chBitMask
specifies which channels to control. The channels are represented in order, with the lowest bit representing channel 0. Only channels whose representative bits are standing are controlled.
The capture bit mask capBitMask
specifies which captures to control. SND_CAPTURE_0
would be ( 1 << SND_CAPTURE_0
), while SND_CAPTURE_1
would be ( 1 << SND_CAPTURE_1
). Enter with a logical OR to specify both.
The Sound alarm bit mask alarmBitMask
specifies which Sound alarms to control. The alarms are represented in order, with the lowest bit representing alarm 0. Only alarms whose representative bits are standing are controlled.
This function is an ARM7 reserved function. After this function is called, processing occurs only after the command is issued with the SND_FlushCommand
function.
When it is necessary to synchronize something with the completion of the process, first use SND_GetCurrentCommandTag
to obtain the command tag immediately after calling this function. After the command is issued, use the command tag and call either the SND_IsFinishedCommandTag
or SND_WaitForCommandProc
function to confirm that the process has finished or to wait for it to complete.
