INITIALIZATION AND PROGRAMMING EXAMPLES
$0200
Freescale Semiconductor, Inc.
two 32Kx8 RAM chips using the Chip Selects.
memory will start at address $30000 and will be both
byte and word readable/writable.
This program assumes that the RAM to be installed
(such as MCM60L256AP85 or MCM6206P85) have
access times of 85 ns and require no wait states.
The DSACK field of the Chip Select Option Registers
may need to be adjusted for chips that have faster or
slower access times.
