(1) Differences between the emulator and MCUs

IMPORTANT

z The emulator initializes the MCU internal register to the following values. Initialization starts when the power

switch is turned ON or MCU is reset.

R0 = 00000000 R1 = 00000000 R2 = 00000000 R3 = 00000000 R4 = 00000000

R5 = 00000000 R6 = 00000000 R7 = 00000000 R8 = 00000000 R9 = 00000000

R10 = 00000000 R11 = 00000000 R12 = 00000000 R13 = 00000000 R14 = 00000000

R15 = 00000100 SPI = 00000100 SPU = 00000100 BPC = 00000000 PC = 00000000

ACCH = xxxxxxxx ACCL = xxxxxxxx

PSW = 00000000

(2) MCU signals connected to the SDI MCU control interface connector (Section 3.2)

No.
