MT9075A

4-193

Page 0FH, addresses 10H to 1FH contain the 16 bytes of transmit message buffer zero

Page 10H, addresses 10H to 1FH contain the 16 bytes of transmit message buffer one

Receive Message Mode Buffer Zero and One (Pages 11H and 12H)

Pages 11H and 12H - Receive Message Buffer 0 and 1 respectively, contain 32 bytes of memory. Each byte is

updated once per frame by the equivalent PCM 30 channel from the receive data stream.
