(10) Warnings that Apply to H8/36064 Group Programming
(a) The description given in the hardware manual is “Initial value: 0. Reserved. These bits are always read as
0”. However, the description in the emulator manual is “Always specify 0. These bits are always read as
the specified values”.
Table 8.52 Differences between the H8/36064 Group Products (1)
Target Address Register Name Bits
H'FFE0 Port mode register 1 0
H'FFE1 Port mode register 5 7 and 6
H'FFE2 Port mode register 3 7, 6, and 5
H'FFF1 System control register 2 6
H'FFF4 Interrupt enable register 1 6
H'FFF5 Interrupt enable register 2 7 and 6
H'FFF9 Module standby control register 1 7, 2, and 0
H'FFFA Module standby control register 2 6, 5, and 3
(b) The description given in the hardware manual is “Reserved”. However, the description in the emulator
manual is “Always specify 0. These bits are always read as the specified values”.

Target Address Register Name Bits
H’FFFB Module Standby Control Register 3 0
(c) The hardware manual shows registers at the addresses given below. For these locations, however, the
applicable description in the emulator manual is “Writing has no effect. These bits are always read as
undefined values”, because there are no registers at these locations of the emulator.
Table 8.54 Differences between the H8/36064 Group Products (3)
Target Address Register Name Bits
H’F730 Low-voltage-detection control register 7 to 0
H’F731 Low-voltage-detection status register 7 to 0
H’FF90 Flash memory control register 1 7 to 0
H’FF91 Flash memory control register 2 7 to 0
H’FF92 Flash memory power control register 7 to 0
H’FF93 Erase block register 1 7 to 0
H’FF9B Flash memory enable register 7 to 0
(d) Although the hardware manual says that an initial value is 1, the compact emulator’s initial value is “0”.
These bits must always be set to 1, when counting up the watchdog timer.

Target Address Register Name Bits
H’FFC0 Timer Control/Status Register WD 2
(e) Although the hardware manual says that the allowable output high current is 5.0 mA, it is 2.0 mA in the
E6000 emulator.
