Section 3 Software Specifications when Using the SH7211

3.1 Differences between the SH7211 and the Emulator

1. When the emulator system is initiated, it initializes the general registers and part of the control

registers as shown in table 3.1. The initial values of the actual SH7211 registers are undefined.

When the emulator is initiated from the workspace, a value to be entered is saved in a session.

Table 3.1 Register Initial Values at Emulator Link Up

R0 to R14 H'00000000

R15 (SP) Value of the SP in the power-on reset vector table

PC Value of the PC in the power-on reset vector table

SR H'000000F0

GBR H'00000000

VBR H'00000000

TBR H'00000000

MACH H'00000000

MACL H'00000000

PR H'00000000

Note: When a value of the interrupt mask bit in the SR register is changed in the [Registers]

window, it is actually reflected in that register immediately before execution of the user

program is started. It also applies when the value is changed by the REGISTER_SET

command.

2. The emulator uses the H-UDI; do not access the H-UDI.

3. Low-Power States (Sleep, Software Standby, and Module Standby)

• When the emulator is used, the sleep state can be cleared with either the clearing function or

with the [STOP] button, and a break will occur.

• The memory must not be accessed or modified in software standby state.

• Do not stop inputting the clock to the H-UDI module by using the module standby function.
