17.2.8
ODR2 is an 8-bit readable/writable register to the slave processor, and an 8-bit read-only register
to the host processor. The ODR2 contents are output on the host data bus when HA0 is low, CS2
is low, and IOR is low.
The initial values of ODR2 after a reset and in standby mode are undetermined.
17.2.9
STR2 is an 8-bit register that indicates status information during host interface processing. Bits 3,
1, and 0 are read-only bits to both the host and slave processors.
STR2 is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 4 and Bit 2—Defined by User (DBU): The user can use these bits as necessary.
Bit 3—Command/Data (C/D D D D ): Receives the HA0 input when the host processor writes to IDR2,
and indicates whether IDR2 contains data or a command.
