Section 18 Host Interface
18.2.4
IDR1 is an 8-bit read-only register to the slave processor, and an 8-bit write-only register to the
host processor. When CSn (n = 1 to 4) is low, information on the host data bus is written into
IDRn at the rising edge of IOW. The HA0 state is also latched into the C/D bit in STRn to indicate
whether the written information is a command or data.
The initial values of IDR1 after a reset and in standby mode are undetermined.
18.2.5
ODR1 is an 8-bit readable/writable register to the slave processor, and an 8-bit read-only register
to the host processor. The ODRn contents are output on the host data bus when HA0 is low, CSn
(n = 1 to 4) is low, and IOR is low.
The initial values of ODR1 after a reset and in standby mode are undetermined.
