Functional Differences Between
MSC8101 (Mask 2K42A) and MSC8103
(Mask 2K87M)
1 Introduction
This document describes the differences between MSC8101
mask set 2K42A and MSC8103 mask set 2K87M. These
differences include:
• System Interface Unit (SIU) changes:
— Internal Memory Map Register (IMMR) MASKNUM
field value
— Addition of the Internal Memory Map Mirror Register
(IMMMR)
• Reset changes:
— Modes
— Hard Reset Configuration Word (HRCW) layout
• Boot source changes
• Clock changes
— Clock scheme
— System Clock Mode Register (SCMR)
— Addition of the CLKODIS field to the System Clock
Control Register (SCCR)
— Clock modes
— CLKIN to CLKOUT delay change
— Maximum clock frequencies change
• Memory map addition of IMMMR
• ORx in UPM mode, bit 27 functionality difference
• Host interface (HDI16) changes
• Direct memory access (DMA) controller transfer code
