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
