Analog Front End Control Interface
The Analog Front End Interface is designed to be
connected to the ST70134 Analog Front End
component.
Transmit Interface
The 16 bit words are multiplexed on 4 AFTXD
output signals. As a result 4 cycles are needed to
transfer 1 word. Refer to table 1 for the bit/pin
allocation for the 4 cycles.
The first of 4 cycles is identified by the CLWD
signal. Refer to Figure 23.
Figure 24 :
Transmit Word Timing Diagram
The ST70135A fetches the 16 bit word to be
multiplexed on AFTXD from the Tx Digital
Front-End module.
Receive Interface
The 16 bit receive word is multiplexed on 4
AFRXD input signals. As a result 4 cycles are
needed to transfer 1 word.
Refer to Table 2 for the bit / pin allocation for the 4
cycles. The first of 4 cycles is identified by the
CLWD must repeat after 4 MCLK cycles.
