3.8.3 Reset
N8954DSC
The reset input (RST*) is an active-low input that presets all IMR bits and clears
all interrupt enables (disabling the IRQ* output). The following registers are reset
synchronously by the GCLK to a value of 0x00: ISR, RCMD_1, RCMD_2,
DFRAME_LEN, SYNC_WORD, CMD_1, PFRAME_LEN, and
PCM_FORMAT. This means the f
be applied to the RST* pin. When a reset is applied to the RST* pin, the IMR is
asynchronously set to a value of 0xFF.
The following configuration of the Bt8954 is not valid:
NUM_SBITS [TCMD2] = 0
EXTRA_Z_BIT [CMD_1] = 1
NUM_CHAN [PCM_FORMAT1] = 0x0B
DFRAME_LEN = 0x58
