Memory Organization
The memory space of the C167CR is configured in a Von Neumann architecture which
means that code memory, data memory, registers and I/O ports are organized within the
same linear address space which includes 16 Mbytes. The entire memory space can be
accessed bytewise or wordwise. Particular portions of the on-chip memory have
additionally been made directly bitaddressable.
The C167CR incorporates 128/32 Kbytes (depending on the derivative) of on-chip mask-
programmable ROM for code or constant data. The lower 32 Kbytes of the on-chip ROM
can be mapped either to segment 0 or segment 1.
2 Kbytes of on-chip Internal RAM (IRAM) are provided as a storage for user defined
variables, for the system stack, general purpose register banks and even for code. A
register bank can consist of up to 16 wordwide (R0 to R15) and/or bytewide (RL0, RH0,
…, RL7, RH7) so-called General Purpose Registers (GPRs).
1024 bytes (2
× 512 bytes) of the address space are reserved for the Special Function
Register areas (SFR space and ESFR space). SFRs are wordwide registers which are
used for controlling and monitoring functions of the different on-chip units. Unused SFR
addresses are reserved for future members of the C166 Family.
2 Kbytes of on-chip Extension RAM (XRAM) are provided to store user data, user stacks,
or code. The XRAM is accessed like external memory and therefore cannot be used for
the system stack or for register banks and is not bitaddressable. The XRAM permits
16-bit accesses with maximum speed.
In order to meet the needs of designs where more memory is required than is provided
on chip, up to 16 Mbytes of external RAM and/or ROM can be connected to the
microcontroller.
