 | |
| 
 | |
| Setting the sample rates on Layla24 is somewhat schizophrenic.
 | |
| 
 | |
| For standard rates, it works exactly like Mona and Gina24.  That is, for
 | |
| 8, 11.025, 16, 22.05, 32, 44.1, 48, 88.2, and 96 kHz, you just set the
 | |
| appropriate bits in the control register and write the control register.
 | |
| 
 | |
| In order to support MIDI time code sync (and possibly SMPTE LTC sync in
 | |
| the future), Layla24 also has "continuous sample rate mode".  In this mode,
 | |
| Layla24 can generate any sample rate between 25 and 50 kHz inclusive, or
 | |
| 50 to 100 kHz inclusive for double speed mode.
 | |
| 
 | |
| To use continuous mode:
 | |
| 
 | |
| -Set the clock select bits in the control register to 0xe (see the #define
 | |
|  below)
 | |
| 
 | |
| -Set double-speed mode if you want to use sample rates above 50 kHz
 | |
| 
 | |
| -Write the control register as you would normally
 | |
| 
 | |
| -Now, you need to set the frequency register. First, you need to determine the
 | |
|  value for the frequency register.  This is given by the following formula:
 | |
| 
 | |
| frequency_reg = (LAYLA24_MAGIC_NUMBER / sample_rate) - 2
 | |
| 
 | |
| Note the #define below for the magic number
 | |
| 
 | |
| -Wait for the DSP handshake
 | |
| -Write the frequency_reg value to the .SampleRate field of the comm page
 | |
| -Send the vector command SET_LAYLA24_FREQUENCY_REG (see vmonkey.h)
 | |
| 
 | |
| Once you have set the control register up for continuous mode, you can just
 | |
| write the frequency register to change the sample rate.  This could be
 | |
| used for MIDI time code sync. For MTC sync, the control register is set for
 | |
| continuous mode.  The driver then just keeps writing the
 | |
| SET_LAYLA24_FREQUENCY_REG command.
