10.14.4 Read/Write Configuration
SYNOPSIS
unsigned long readw_bus8(unsigned long source)
void writew_bus8(unsigned long dest,
unsigned long 32-bit)
DESCRIPTION
The MPC106 defines the address range FF80,0000
16
to FFFF,FFFF
16
as 8-bit system
ROM space. The monitor’s memory commands may not be used to write 32-bit
values to the registers in this space because 8-bit access is required. Instead, the
function
writew_bus8 provides the necessary 8-bit access to the space. Func-
tionality is undefined if Address is not long-word aligned.
NOTE. The MPC106 supports 8-, 16-, and 32-bit reads in the ROM, so
readw_bus8 is not necessary. However, it is included for compatibil-
ity with other Artesyn products.
10.14.5 Display Processor Temperature
SYNOPSIS
void DisplayTemp(void)
DESCRIPTION
DisplayTemp successively approximates the processor junction temperature
from the Thermal Management Unit. It displays in real time the temperature in
degrees Celsius. The resolution of the thermal sensor is 4° C. If the “ThermPro-
tect” NVRAM parameter is enabled and MSR[EE] is not disabled, the monitor puts
the processor into permanent sleep mode when the junction temperature exceeds
100° C. The application can change this behavior at 100° C by connecting a new
interrupt handler to vector 1700
16
. “ThermProtect” is disabled by default.
