ICEport
sc_ICEDop[31:0]
SCbus Output Data Bus
This is the SCbus output data bus. For read operations
from the ICEport, the ICEport will place data onto this
bus. Data on this bus is valid for one clock cycle and only
when the sc_ICEDoEp signal is asserted.
Output
sc_ICEDoEp
SCbus Output Data Valid
This signal is used to drive three-state buffers in the
LR4500. Asserting this signal indicates that the
sc_ICEDop[31:0] bus is valid during the current cycle.
sc_ICEDoEp is asserted for read transactions only and
lasts for only one SCLKp cycle.
Output
sc_ICEINTp
ICEport Interrupt
If this signal is enabled by the RxRXRDYPe bit in the
RX Setup register, the ICEport asserts sc_ICEINTp once
it receives a valid byte of off-chip data. sc_ICEINTp is
input to the SCLC module, which then generates an
interrupt to the core in the SCLC.
Output
sc_ICERDYp
ICEport Ready
Asserting this signal HIGH informs the core or the SCLC
module that the current transaction on the SCbus has
finished. sc_ICERDYp encompasses both the SCB32n
and SCBRDYn SCbus control signals.
Output
9.4.3 ICEport Scan and Clocking I/O Signals
These signals are the scan and clocking I/O signals for the ICEport.
ICECLKp
ICE Serial Bit Clock Rate x 16
The ICEport requires that this off-chip signal have a clock
frequency 16 times greater than the serial
transmit/receive rate. The ICEport assumes each
serial/transmit bit is 16 ICECLKp cycles long.
Input
ICERXp
RX Serial Bit Receive
This is an off-chip input that holds the UART serial input
data stream. Each received bit is 16 ICECLKp cycles
long.
