8.10 Timer Module Signals
The following signals are external interface to the two general-purpose SCF5249 timers. These 16-bit
timers can capture timer values, trigger external events, or internal interrupts, or count external events.
These pins can be reused as GPO or GPI. Registers GPIO-FUNCTION and GPIO1-FUNCTION must be
programmed for this.
8.11 Serial Audio Interface Signals
All serial audio interface signals can be programmed to serve as general purpose I/Os or as serial audio
interface signals. The function is programmed using GPIO-FUNCTION and GPIO1-FUNCTION
registers.
NOTE
The LRCK3 and SCLK3 signals are only used in the 160 MAPBGA
package..
Table 7. Serial Module Signals
Serial Module Signal
Description
Receive Data
The RXD1_GPI27 and RXD2/ADIN2/GPI28 are the inputs on which
serial data is received by the DUART. Data is sampled on RxD[1:0] on
the rising edge of the serial clock source, with the least significant bit
received first.
Transmit Data
The DUART transmits serial data on the TXD1/GPO27 and
TXD2/GPO28 output signals. Data is transmitted on the falling
edge of the serial clock source, with the least significant bit
transmitted (LSB) first. When no data is being transmitted or
the transmitter is disabled, these two signals are held high.
TxD[1:0] are also held high in local loopback mode.
Request To Send
The RTS1/GPO30 and RTS2/GPO31 request-to-send outputs
indicate to the peripheral device that the DUART is ready to
send data and requires a clear-to-send signal to initiate
transfer.
Clear To Send
Peripherals drive the CTS1/GPI30 and CTS2/ADIN3/GPI31
inputs to indicate to the SCF5249 serial module that it can
begin data transmission.

Serial Module Signal
Description
Timer Input
Users can program the TIN0/GPI33 and TIN1/GPIO23 inputs
as clocks that cause events in the counter and prescalars.
They can also cause capture on the rising edge, falling edge,
or both edges.
Timer Output
The TOUT0/GPO33 and TOUT1/ADOUT/GPO35
programmable outputs pulse or toggle on various timer events.
