• Manufacturer Part Number: EM78159NAS
• Description: 8-Bit Microcontroller with OTP ROM
• Manufacturer: EMC [ELAN Microelectronics Corp]

Product Specification (V1.0) 03.10.2006
(This specification is subject to change without further notice)
4.1.5 R4 (RAM Select Register)
Bits 0~5
Bits 6~7
The “Z” flag of R3 will set to “1” when the R4 content is equal to “3F.” When R4=R4+1,
the R4 content will select “R0.”
4.1.6 R5 ~ R6 (Port 5 ~ Port 6)
R5 and R6 are I/O registers. Only the lower 7 bits of R5 are available.
4.1.7 RD (Manual Calibration Register)
In EM78P159N: The register does not exist in real chip.
In ICE159N Simulator: C3 ~ C0 are IRC calibration bits in MCIRC mode.
Bit 3 ~ Bit 0 (C3 ~ C0): are the Calibrators of internal RC mode
Bits 4~7: Not used

NOTES:
1. Frequency values shown are theoretical and taken from an instance of a high
2. Similar way of calculation is also applicable to Low Frequency mode.
C2
are used to select registers (Address: 00~06, 0F~3F) in the indirect
addressing mode.
Not used (read only). Set these bits to “1” all the time.
