[DCE_CTS_A]
[PCM_TSC_A]
PIO17
STI
DCE Clear-To-Send Channel A indicates to the channel A DCE
interface that an external serial interface is ready to receive data.
[DCE_CTS_A] and [DCE_RTR_A] provide the handshaking for
the channel A DCE interface.
[DCE_RTR_A]
PIO18
O
DCE Ready-to-Receive Channel A indicates to an external
serial interface that the internal channel A DCE interface is ready
to accept data. [DCE_CTS_A] and [DCE_RTR_A] provide the
handshaking for the channel A DCE interface.
HDLC Channel B (DCE)
[DCE_RXD_B]
[PCM_RXD_B]
PIO36
STI
DCE Receive Data Channel B is the serial data input pin for
the channel B DCE interface.
[DCE_TXD_B]
[PCM_TXD_B]
PIO37
OD-
O
DCE Transmit Data Channel B is the serial data output pin for
the channel B DCE interface.
[DCE_RCLK_B]
[PCM_CLK_B]
PIO40
STI
DCE Receive Clock Channel B provides the receive clock to
the channel B DCE interface. If the same clock is to be used for
both transmit and receive, this pin should be tied to the
[DCE_TCLK_B] pin externally.
[DCE_TCLK_B]
[PCM_FSC_B]
PIO41
STI
DCE Transmit Clock Channel B provides the transmit clock to
the channel B DCE interface. If the same clock is to be used for
both transmit and receive, this pin should be tied to the
[DCE_RCLK_B] pin externally.
[DCE_CTS_B]
[PCM_TSC_B]
PIO38
STI
DCE Clear-To-Send Channel B indicates to the channel B DCE
interface that an external serial interface is ready to receive data.
[DCE_CTS_B] and [DCE_RTR_B] provide the handshaking for
the channel B DCE interface.
[DCE_RTR_B]
PIO39
O
DCE Ready-to-Receive Channel B indicates to an external
serial interface that the internal channel B DCE interface is ready
to accept data. [DCE_CTS_B] and [DCE_RTR_B] provide the
handshaking for the channel B DCE interface.
HDLC Channel C (DCE)
[DCE_RXD_C]
[PCM_RXD_C]
PIO42
STI
DCE Receive Data Channel C is the serial data input pin for
the channel C DCE interface.
[DCE_TXD_C]
[PCM_TXD_C]
PIO43
OD-
O
DCE Transmit Data Channel C is the serial data output pin for
the channel C DCE interface.
[DCE_RCLK_C]
[PCM_CLK_C]
PIO22
STI
DCE Receive Clock Channel C provides the receive clock to
the channel C DCE interface. If the same clock is to be used for
both transmit and receive, this pin should be tied to the
[DCE_TCLK_C] pin externally.
[DCE_TCLK_C]
[PCM_FSC_C]
PIO23
STI
DCE Transmit Clock Channel C provides the transmit clock to
the channel C DCE interface. If the same clock is to be used for
both transmit and receive, this pin should be tied to the
[DCE_RCLK_C] pin externally.
[DCE_CTS_C]
[PCM_TSC_C]
PIO44
STI
DCE Clear-To-Send Channel C indicates to the channel C DCE
interface that an external serial interface is ready to receive data.
[DCE_CTS_C] and [DCE_RTR_C] provide the handshaking for
the channel C DCE interface.
