FUNCTIONS
GCI Bus
GCI Bus Data Clock of the frequency: 1.536 MHz. Needs
external pull-up.
GCI Bus Frame Synchronization Clock: 8 KHz. Needs
external pull-up.
GCI Bus Data Downstream: Slave mode-input, master
mode-output. Needs external pull-up.
GCI Bus Data Upstream : Slave mode - output, master
mode - input. Needs external pull-up.
PCM Interface
PCM port 1 frame synchronization signal, with 8 KHz
repetition rate and 8 bit pulse width.
