TP3465V. Datasheet PCM interface supports the external PCM codec with CVSD Bluetooth codec functionality. For the external PCM codec, it support 8-bit A/u-law PCM and 13- or 14-bit 8KHz linear PCM in both master or slave mode. For 8-bit A/u-law format, it supports one, two and four channels simultaneously. TP3465V.

However, halting the internal clock register updating process does not affect clock accuracy. Updating is halted when a one is written into the read bit, bit 6 0f the century register, see Table 2. As long as a one remains in that position, updating is halted. After a halt is issued, the registers reflect the count, that is day, date, and time that was current at the moment the halt command was issued. However, the internal clock registers of the double-buffered system continue to update so that the clock accuracy is not affected by the access of data. All the DS1747 registers are updated simultaneously after the internal clock register updating process has been re-enabled. Updating is within a second after the read bit is written to zero. The READ bit must be set to a zero for a minimum of 500 Iis to ensure the external registers will be updated. r
