UART_RTS
A CMOS output with a weak
internal pull-up. This pin can be
used to implement RS232
hardware flow control where RTS
(request to send) is an active low
indicator. The UART interface
requires an external RS232
transceiver chip.
UART request to send, active
low
Alternative function:
PIO16: Programmable input /
output line 16.
Bidirectional with strong
pull-up
6
UART_CTS
A CMOS input with a weak
internal pull-down. This pin can
be used to implement RS232
hardware flow control where CTS
(clear to send) is an active low
indicator. The UART interface
requires an external RS232
transceiver chip.

SPI_PCM#
Configurated PCM/I2S digital audio
interfa- ce shares the same physical
set of pins with the SPI interface.
SPI_PCM# is a CMOS input with a
weak internal pull-down. When
inputs HIGH level, this set of pins is
used
For SPI interface. When inputs
LOW level, this set of pins is used
for PCM/PIO/I2S interface.
SPI/PCM select input:
0 = PCM/PIO interface
1 = SPI
