I2S Sample Counter Register
Counts number of samples written to output (L+R counts as one), can be used in software PLL to control audio decode
thread.
31:0 COUNTER[31:0] Counter increments by one for every sample written on output. Counts L+R as one sample in stereo
mode. This counter is more reliable to implement a software PLL because of more periodic behavior.
This counter will be reset to 0 when I2S_CONFIG.ENABLE=0.
