Holtek Semiconductor 

HT46R064D/065D/066D

Enhanced A/D Type 8-Bit OTP MCU with LED Driver

Program Memory

The Program Memory is the location where the user code or program is stored. The device is supplied

with One-Time Programmable, OTP, memory where users can program their application code into the

device. By using the appropriate programming tools, OTP devices offer users the flexibility to freely

develop their applications which may be useful during debug or for products requiring frequent

upgrades or program changes.

Structure

The Program Memory has a capacity of 1K´14 to 4K´15. The Program Memory is addressed by the

Program Counter and also contains data, table information and interrupt entries. Table data, which can

be setup in any location within the Program Memory, is addressed by separate table pointer registers.

Special Vectors

Within the Program Memory, certain locations are reserved for special usage such as reset and

interrupts.

Reset Vector

This vector is reserved for use by the device reset for program initialisation. After a device reset is initiated,

the program will jump to this location and begin execution.

External Interrupt Vector

This vector is used by the external interrupt. If the external interrupt pin on the device receives an edge

transition, the program will jump to this location and begin execution if the external interrupt is

enabled and the stack is not full. The external interrupt active edge transition type, whether high to low,

low to high or both is specified in the CTRL1 register.
