Input/Output Memory Precautions
Table 4. Reserved Memory Map Example
Internal RAM is mainly employed for data and stacks. However, internal RAM also
contains program code for execution. Most ZNEO CPU devices contain some internal
RAM. The top (highest address) of internal RAM is always located at address
The bottom (lowest address) of internal RAM is a function of the amount of internal RAM
available. To determine the amount of internal RAM available, see
on page
The ZNEO CPU supports 8 KB (8,192 bytes) of I/O memory space located at addresses
FF_E000H
ZNEO CPU, the on-chip peripherals, and the I/O ports. Refer to the device-specific
Product Specification for descriptions of the peripheral and I/O control registers. Attempts
to read or execute from unavailable I/O memory addresses returns
to unavailable I/O memory addresses produce no effect.
Some control registers within the I/O memory provide read-only or write-only access.
When accessing these read-only or write-only registers, ensure that the instructions do not
attempt to read from a write-only register, or conversely write to a read-only register.
Some registers are reserved in 8 KB of I/O memory for the ZNEO CPU control. These
ZNEO CPU control registers are listed in
the operation of the ZNEO CPU control registers, refer to ZNEO CPU User Manual
(UM0188), available for download at www.zilog.com.
