How to read internal I/O register tables
Bit Numbers: Each register is connected with an internal bus of 16-bit
wide, so the bit numbers of the registers located at even
addresses are D0-D7, and those at odd addresses are
D8-D15.
State of Register at Reset: Represents the initial state of each register
immediately after reset with hexadecimal numbers
(undefined bits after reset are indicated each in column .)
At read:
... read enabled
? ... read disabled (read value invalid)
0 ... Read always as 0
1 ... Read always as 1
{ At write:
: Write enabled
: Write enable conditionally
(include some conditions at write)
-
: Write disabled (Written value invalid)
