Table 1: Micro-controller Access Signals
PARAMETER
PIN
TYPE
DESCRIPTIONS
AD[7:0]
4, 3, 2,
1, 94,
93, 92,
91
IO
Address and data bus. This is the multiplexed address and
data bus used for micro-controller interface
ALE
84
IN
Address Latch Enable. Access address is latched at the falling
edge of the ALE. The address specifies the on-chip register
being accessed by the micro-controller.
CS
97
IN
Chip Select. This signal is asserted during a micro-controller
access cycle.
IRQ
85
OUT
Interrupt Request. It is asserted by the W9330F to interrupt the
system micro-controller at certain operation points. Interrupt is
generated at the end of each transmit frame, the end of each
receive frame, and when frame error is detected.
RD
89
IN
Read Control. When
RD
is asserted, read data is driven on to
the AD[7:0] bus by the W9330F.
WR
90
IN
Write Control. When
WR
is asserted, write data on the AD[7:0]
bus is sampled by the W9330F.
Table 2: Codec Interface
PARAMETER
PIN
TYPE
DESCRIPTIONS
COD_CLK
67
OUT
Codec transmit and receive clock. It is used by the Codec chip
to sample received data and generate transmit data. This
signal is generated from the main operating frequency and is
600 KHz.
COD_SYNC
68
OUT
Codec Synchronization signal. This is a 8 KHz framing clock
signal used by the Codec to synchronized transmit and receive
data. COD_SYNC is synchronous with COD_CLK and is
generated from the main operating frequency.
DR
66
OUT
Received Data. Voice data to be sampled by the Codec. It is
sampled by the Codec chip at the falling edge of COD_CLK at
the beginning of each frame.
DT
65
IN
Transmit data. Voice data generated by the Codec for
transmission. It is generated by the Codec at the rising edge of
COD_CLK.
