EM78P153K
8-Bit Microcontroller with OTP ROM
1 General Description
The EM78P153K is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS
technology. The device has an on-chip 1024×13-bit Electrical One Time Programmable Read Only Memory
(OTP-ROM). It provides a protection bit to prevent intrusion of user’s OTP memory code. Fifteen Code
option bits are also available to meet user’s requirements.
With enhanced OTP-ROM features, the EM78P153K provides a convenient way of developing and verifying
user’s programs. Moreover, this OTP device offers the advantages of easy and effective program updates,
using development and programming tools. Users can avail of the ELAN Writer to easily program their
development code.

8-Bit Microcontroller with OTP ROM
5.1.5 R4 (RAM Select Register)
Bits 7 ~ 6 are not used (Read only).
Bits 7 ~ 6 set to “1” at all time.
Bits 5 ~ 0 are used to select registers (Address: 0x00 ~ 0x06, 0x0F ~ 0x2F) in
indirect addressing mode.
See the Data Memory Configuration in Figure 5-3.
5.1.6 R5 ~ R6 (Port 5 ~ Port 6)
R5 and R6 are I/O registers.
Only the lower 4 bits of R5 are available.
The upper 4 bits of R5 are fixed to “0”.
P63 is input only.
5.1.7 RF (Interrupt Status Register)

EXIF
ICIF
Note: “1“ means with interrupt request
“0“ means no interrupt occurs
Bit 0
TCIF
Bits 7 ~ 3: Not used. Set to “0” at all time.
Bit 2 (EXIF): External Interrupt Flag. Set by a falling edge on the /INT pin, reset by
software.
Bit 1 (ICIF): Port 6 input status change interrupt flag. Set when Port 6 input changes,
reset by software.
Bit 0 (TCIF): TCC Overflow Interrupt Flag. Set when TCC overflows, reset by
software.
RF can be cleared by instruction but cannot be set.
IOCF is the interrupt mask register.
NOTE
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.
