Slave DSP Bit I/O
The slave DSP of the DS1103 provides I/O with the following pin
names:
n Slave DSP Bit I/O Unit
n SADCH1, SADCH2, SADCH9, SADCH10
n STMRDIR, STMRCLK, STINT1, STINT2, SPDPINT, SADCSOC, SXF,
SBIO
n SPWM7 ... SPWM9
n ST1PWM ... ST3PWM
n SCAP1 ... SCAP4
Due to the board's limited number of I/O pins, the pins
used to provide the slave DSP bit I/O signals are shared
with other I/O signals of the slave DSP.
n Slave DSP ADC Unit
n SADCH1 ... SADCH16
n Slave DSP Timing I/O Unit
n SPWM1 ... SPWM9
n ST1PWM ... ST3PWM
n SCAP1 ... SCAP4
n
Slave DSP Serial Peripheral Interface (SPI)
n SSOMI, SSIMO, SSTE, SSCLK
n
Slave DSP Serial Interface
n SRXD, STXD, SRXD
