BCLK

I Bulk -data clock (ZR36504uses this clock for both Audio CODEC

and Bulk Data). This clock must be set to 2.024MHz for proper

operation with ZR36505.

I/O General Programmable I/O pins. Each of these 2 pins has a 5-

volt Tolerant Open Drain output, and it is supposed to be

connected to an external pull-up resistor. The host uses these

pins as programmable output ports by writing '0' or '1'. By writing

'1' and read back, the host can use these pins as input ports - as

this allows any external source to force the pull-up resistor.

These outputs are set to high -z upon Power-On or Soft Reset.

The pin IO-1 is also used as the input for IRD data. This pin is

internally sampled at 4KHz sampling rate.

I/O This pin is used for sending and receiving serial control data

between the ZR36505 (slave) and ZR36504(master). It operates

in the LRNACK mode of operation (refer to the ZR36504data

sheet). This pin is Open Drain, and is set to high-z upon Power-

On or Soft Reset.

I This pin is used as the sampling clock for sending and receiving

serial control data between the ZR36505 (slave) and

ZR36504(master). It operates in the LRNACK mode of

operation (refer to the ZR36504data sheet).
