1. Direct addressing resources
1) Direct addressing resources (registers only)
2) Indirect addressing resources (registers and memory)
Table 1. Direct Addressing Register Mapping
Note) 1. CHIPCTL0 is only reset by a hardware reset (setting the external pin NRST low).
Internal Resource Mapping
The MN85571AC has two types of internal resources that are accessed by the external host with different methods.
These are accessed by specifying the address to the external pins HA[3:0].
Table 1 shows the address mapping for the direct addressing resources.
HA[3 : 0]
are 16-bit registers.

2. Chip operation is not guaranteed after access to any of the reserved direct addressing registers.
3. The symbols r and w indicate read and write as seen from the external host.
4. Accesses to registers other than CHIPCTL0 are invalid in the reset state (software reset).
5. The CHIPCTL0, CHIPST0, CHIPST1, STMASK, INADR0, and DIFPTR registers can all be read in the hold, slave, and
These resources are mainly used for controlling this device and indicating the internal state of the device. These
These are memory and other resources that mainly consist of parameter setting registers used at initialization and
The symbol r alone indicates a read-only register, and r/w indicates the both read and write are possible.
All register accesses are invalid in the hardware reset state.
