3. Assert /RESETP and turn Vcc (main) on.
4. After the power has been stable, negate the /CA pin.
5. Negate /RESETP, and the U standby state is cancelled.
6. Before the program execution is restarted from the reset vector, the E10A-USB debugging
function, which has been set in the [Recovery Information] page in the [Configuration] dialog
box, is recovered. During this period, the HEW cannot operate.
Notes: 1. For entering or canceling the U standby state, refer to the section of low power mode
in the SH7339 Hardware Manual.
2. When Vcc (main) is turned on in the U standby state, set the TCK value to less than
the number of peripheral module clocks and select [Configuration dialog information]
in the [Recovery Information] page. If this is not selected, the TCK value will be as
follows:
When HS0005KCU01H or HS0005KCU02H is used: TCK = 0.625 MHz
3. After the /CA pin has been negated, if /RESETP is not input for about 30 seconds, a
timeout error will occur.
4. Software breakpoints that have recovered from the U standby state remain to be set on
the memory. However, the contents displayed in the [Breakpoint] sheet of the
[Eventpoint] window may be different from the actual points when the contents of
memory are initialized by the control of Vcc (main). In this case, clear all the
breakpoints and set them again.
5. In functions for which conditions were not recovered by a selection in [Recovery
information], the settings made will not be the same as the contents displayed in a
dialog box or command after the recovery from the U standby state until when the
user program is halted.
6. If [User] is set in the [UBC mode] list box in the [Configuration] dialog box, Break
Condition (UBC) and Trace Acquisition Condition (AUD) cannot be selected.
7. A noise filter is provided in the emulator to prevent malfunction due to noises of the
/CA pin. It takes about 70 ns from assertion (negation) of /CA to reflection to the
emulator. Therefore, set 70 ns or more periods during assertion to negation of /CA.
8. When the U standby state has been cancelled, before the program execution is
restarted from the reset vector, the E10A-USB debugging function, which has been set
in the [Recovery Information] page in the [Configuration] dialog box, is recovered.
During this period, the HEW cannot operate.
When the debugging functions except for [Configuration dialog information] are not
recovered in the [Recovery Information] page, the following waiting time will be
generated before the user program is reexecuted:
Frequency: 833 MHz (Pentium® III)
OS: Windows 2000
Operating state of SH7339: 20-MHz input clock, 1.25-MHz TCK value
Waiting time: Approximately 28 ms
