4.6.7 Precautions for the H8/36064 Series

(1) The hardware manual says "Initial value = 0. These are reserved bits. When read, they always show the value 0." On
the other hand, the compact emulator stipulates that these bits must always be set to 0, and that when read, these bits
show the set value.

H'FFE1
H'FFE2
H'FFF0
H'FFF1
H'FFF4
H'FFF5
H'FFF9
H'FFFA
(2) Although these bits in the hardware manual are reserved bits, the compact emulator stipulates that these bits must
always be set to 0, and that when read, these bits show the set value.
H'FFFB
(3) Although the hardware manual says that registers are located at the addresses shown below, the compact emulator
stipulates that writing to the addresses has no effect, and that when read, they show indeterminate values. This is
because no registers exist at these addresses in the compact emulator.
H'F730
H'F731
H'FF90
H'FF91
H'FF92
H'FF93
H'FF9B
(4) 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.
H'FFC0
(5) Although these bits in the hardware manual are reserved bits, the compact emulator stipulates that these bits must
always be set to 0.
H'FFFFE4
H'FFFFE5
H'FFFFEA
H'FFFFEB
(6) Although the hardware manual says that the allowable output high current is 5.0 mA, it is 2.0 mA in the compact
emulator.
