9. Port
The AUD pins are multiplexed as shown in table 2.2.
Table 2.2 Multiplexed Functions
Function 1 Function 2
PTL1/RAC-DCD#/DCD0# AUDCK (AUD)
PTL2/RAC-DSR#/DSR0# AUDSYNC (AUD)
PTT7/PWMX7/MD2 AUDATA3 (AUD)
PTT6/PWMX6 AUDATA2 (AUD)
PTT5/PWMX5 AUDATA1 (AUD)
PTT4/PWMX4 AUDATA0 (AUD)
Note: Function 1 can be used when the AUD pins of the device are not connected to the
emulator.
When the AUD trace is enabled, the emulator changes settings so that function 2 is forcibly
used.
10. UBC
When [User] is specified in the [UBC mode] list box in the [Configuration] dialog box, the
UBC can be used in the user program.
Do not use the UBC in the user program as it is used by the emulator when [EML] is specified
in the [UBC mode] list box in the [Configuration] dialog box.
11. Memory Access during Break
In the enabled MMU, when a memory is accessed and a TLB error occurs during break, it can
be selected whether the TLB exception is controlled or the program jumps to the user
exception handler in [TLB Mode] in the [Configuration] dialog box. When [TLB miss
exception is enable] is selected, a “Communication Timeout error” will occur if the TLB
exception handler does not operate correctly. When [TLB miss exception is disable] is
selected, the program does not jump to the TLB exception handler even if a TLB exception
occurs. Therefore, if the TLB exception handler does not operate correctly, a “Communication
Timeout error” will not occur but the memory contents may not be correctly displayed.
12. Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be 5 MHz.
If the [Search the best JTAG clock] option is used when the emulator is initiated, the TCK
value will be initialized as a value that has been automatically acquired.
