PIN NAME
PIN DESCRIPTION
SONSDH/
GPIO4
IOPD
SONET/SDH Frequency Select Input/General-Purpose I/O 4. When
RST goes high the state
of this pin sets the reset-default state of MCR3:SONSDH, MCR6:DIG1SS, and MCR6:DIG2SS.
After
RST goes high, this pin can be used as a general-purpose I/O pin. GPCR:GPIO4D
configures this pin as an input or an output. GPCR:GPIO4O specifies the output value.
GPSR:GPIO4 indicates the state of the pin.
Reset latched values:
0 = SDH rates (N x 2.048MHz)
1 = SONET rates (N x 1.544MHz)
INTREQ/LOS
O3
Interrupt Request/Loss of Signal. Programmable (default: INTREQ). The INTCR:LOS bit
determines whether the pin indicates interrupt requests or loss of signal (i.e., loss of selected
reference).
INTCR:LOS = 0: INTREQ mode
The behavior of this pin is configured in the INTCR register. Polarity can be active high or
active low. Drive action can be push-pull or open drain. The pin can also be configured as
a general-purpose output if the interrupt request function is not needed.
INTCR:LOS = 1: LOS mode
This pin indicates the real-time state of the selected reference activity monitor (see Section
Table 6-4. SPI Bus Mode Pin Descriptions
See Section 7.9 for functional description and Section 10.4 for timing specifications.
PIN NAME
PIN DESCRIPTION
CS
IPU
Chip Select. This pin must be asserted (low) to read or write internal registers.
SCLK
I
Serial Clock. SCLK is always driven by the SPI bus master.
SDI
I
Serial Data Input. The SPI bus master transmits data to the device on this pin.
SDO
O
Serial Data Output. The device transmits data to the SPI bus master on this pin.
CPHA
I
Clock Phase. See Figure 7-4.
0 = Data is latched on the leading edge of the SCLK pulse.
1 = Data is latched on the trailing edge of the SCLK pulse.
Table 6-5. JTAG Interface Pin Descriptions
See Section 9 for functional description and Section 10.5 for timing specifications.
PIN NAME
PIN DESCRIPTION
JTRST
IPU
JTAG Test Reset (Active Low). Asynchronously resets the test access port (TAP) controller. If
not used,
JTRST can be held low or high.
JTCLK
I
JTAG Clock. Shifts data into JTDI on the rising edge and out of JTDO on the falling edge. If
not used, JTCLK can be held low or high.
JTDI
IPU
JTAG Test Data Input. Test instructions and data are clocked in on this pin on the rising edge
of JTCLK. If not used, JTDI can be held low or high.
JTDO
O3
JTAG Test Data Output. Test instructions and data are clocked out on this pin on the falling
edge of JTCLK. If not used, leave unconnected.
JTMS
IPU
JTAG Test Mode Select. Sampled on the rising edge of JTCLK and is used to place the port
into the various defined IEEE 1149.1 states. If not used connect to VDDIO or leave
unconnected.
