8-Bit Microcontroller with OTP ROM
1 General Description
The EM78P153B is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS
technology. The device has an on-chip 102413-bit Electrical One Time Programmable Read Only Memory
(OTP-ROM). It provides three protection bits to prevent intrusion of user’s OTP memory code. Fifteen code
option bits are also available to meet user’s special requirements.
With enhanced OTP-ROM features, the EM78P153B provides a convenient method of developing and
verifying users programs. Moreover, this OTP device offers easy and effective program updates with the
use of development and programming tools. You can avail of ELAN’s Writer to easily program your
development codes.

5.1.7 RF (Interrupt Status Register)
Bit 7
Bit 6
Bit 5
Bit 4
Bit 3
Bit 2
Bit 1
Bit 0
- - - - - EXIF ICIF TCIF
Bits 7 ~ 3: Not used. Set to “0” all the time.
Bit 2 (EXIF): External Interrupt Flag. Set by a falling edge on /INT pin, reset by
0: No interrupt occurs
1: Interrupt is requested
Bit 1 (ICIF): Port 6 input status change interrupt flag. Set when Port 6 input changes,
reset by software.
0: No interrupt occurs
1: Interrupt is requested
Bit 0 (TCIF): TCC Overflow Interrupt Flag. Set when TCC overflows, reset by
0: No interrupt occurs
1: Interrupt is requested
RF can be cleared by instruction but cannot be set.
IOCF is the interrupt mask register.
The result of reading RF is the "logic AND" of RF and IOCF.
5.1.8 R10 ~ R2F
These are all 8-bit general-purpose registers.
5.2 Special Function Registers
5.2.1 A (Accumulator)
Internal data transfer operation, or instruction operand holding usually involves the
temporary storage function of the Accumulator; which is not an addressable register.
5.2.2 CONT (Control Register)
Bit 7
Bit 6
Bit 5
Bit 4
Bit 3
Bit 2
Bit 7 (GP): General purpose register
Bit 6 (/INT): Interrupt Enable flag
0: Masked by DISI or hardware interrupt
1: Enabled by ENI/RETI instructions
Bit 1
Bit 0
