TX_IF1
TX_IF2
AO
Outputs differential signal to the IF output signal pin. Output format is
an open-collector. Only operates in the CDMA/FM talk mode. An
external components pull it up using VDD when operation is not
allowed.
4
TAGC_CONT
AI
DC input for AGC gain control. This input is the PDM control signal
from the modem, which was converted to a digital signal in the R-C
filter. This pin has high impedance when not in operation.

TXD2
TXD3
TXD4
TXD5
TXD6
TXD7
DI
Transmit data input pins for transmit 8-bit D/A converter TXD7 is the
MSB.
19
20
TCLK
TCLKB
DI
Complementary inputs to transmit D/A converter.
24
GPENA
DI
This pin is always on stand-by and is not affected by the SEN's pin
conditions. If this pin changes from low to high when the TCXO is
allowed, GP-ADC starts to operate as well as GPDATA and GPCLK.
25
GPDATA
DO
GP-ADC conversion data output pin. This pin cannot be operated by
the SPI but must be operated by the GPENA pin. On stand-by, the pin
is at low.
26
GPCLK
DO
GP-ADC conversion data synchronization pulse output pin. This pin
cannot be operated by the SPI but must be operated by the GPENA
pin. On stand-by, the pin is at low.
27
28
29
GPIN1
GPIN2
GPIN3
AI
3-analog input terminals. Only the input from one of these is input to
the GP-ADC. The input is selected based on the conditions of the
SMSB/PAON and SLSB/CLK terminals in the SPI restrict mode and
on the register value in the SPI operating mode. On stand-by, it has
high impedance.
30
SMSB/PAON
DI
SEN is the pin for the former bit of the two bits used to select the GP
input in low state. This pin executes the PAON function when SEN=1
and TXMODE_CONT[3] =1 and executes the Tx Puncture mode when
this pin is at low.
31
SEN
DI
Select pin for the use of the SPI BUS. If this pin is at high, the SPI bus
can be used; if low, the SPI bus cannot be used but an external
control pin can be used.
