Technical information

SCI to SPI Peripheral Communication in V850ES Microcontrollers
The data will be shown serially in the two LED digits, scrolling the number through with short
delays between shifts. For example the temperature +123.75ºC would be shown as:
“1 2” hundreds and tens digits
“2 3.” tens and units digits, with decimal point
“3. 7” units digit with decimal point, tenths digit
“7 5” tenths digit, hundredths digit
The temperature –43.275ºC would be shown as
“4 ” minus sign, tens digits
“4 3.” tens digit, units digits with decimal point
“3. 2” units digit with decimal point, tenths digit
“5 7” tenths digit, hundredths digit (fraction after hundredths truncated)
If the number is such that –100 < temp < +100, no hundreds digit will be shown. If the number is
such that –10 < temp < +10, no tens digit will be shown, and a blank or the sign will be displayed.
The temperature +5.00ºC would be shown as:
“ 5.” blank tens digit, units digit with decimal point
“5. 0” units digit with decimal point, tenths digit
“0 0” tenths digit, hundredths digit
The temperature of ±5.00ºC would be shown as:
“– 5.” minus sign, units digit with decimal point
“5. 0” units digit with decimal point, tenths digit
“0 0” tenths digit, hundredths digit
2.7 Applilet's Reference Driver
NEC Electronics’ Applilet program generator can automatically generate C or assembly language source
code to manage peripherals for the NEC Electronics MCUs. See Section 3 for the version of Applilet
used.
Applilet is used to produce the basic initialization code and main function for the program, clock
initialization code, initialization and driver code for the CSI00 and timer TM00 peripherals, and
