IN16C01

16-BIT RISC MICROCONTROLLER

Integral Corp. 

IN16C01

The 16-bit general purpose register. The register can be used as a counter. The register

contents can be analysed by conditional branch instructions and can be decremented

concurrently with an ALU operation. The register is used as a counter in flow mode

instructions.

USER

The 24-bit address register. The register's contents are used as a base address during

external registers access.

SP

The 24-bit general purpose register. The register can contain an address and can be used

to address the data memory as well.

RP

The 24-bit general purpose register. The register can contain an address and can be used

to address the data memory as well.

WORK

The 32-bit general purpose register. The register can be used in integer multiply and

multiply-accumulate operations.

ALU

The 16-bit arithmetic-logic unit with a multiplier. The ALU's two operands are the T and N

registers.

PSW

16-bit processor status word..

2.2 Memory

The microcontroller address space is divided into data and program memory. The

IN16C01 accesses the internal data and program memories concurrently using separate

buses. An external memory access is accomplished via common bus with separate

address and data. The SDI input signal defines the type of the space selected (data or

program). The internal data memory can not be modified.

The CPU core addresses 16-bit words in memory. One clock cycle is needed to read or

write a memory word.

The microcontroller supports a possibility to write high/low bytes in a 16-bit word. There

are special prefixes in the IN16C01 instruction set: BYTE_L and BYTE_H. These prefixes

control WRL and WRH signals.
