C161RI
Memory Organization
The memory space of the C161RI 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.
1 KByte of on-chip Internal RAM is 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.
In order to meet the needs of designs where more memory is required than is provided on chip, up
to 8 MBytes of external RAM and/or ROM can be connected to the microcontroller.
