Sample Program for the Multi-pulse Generator
●
Processing
•
An output in PPG is directed to OPT0 and an inverted output in PPG is directed to OPT1 when write
timing interrupt is generated.
•
OPDBR0 write method is used for data transfer to output data register OPDR.
•
The 16-bit PPG timer is used in PWM and is started with a software trigger.
•
EI
2
OS is not used.
•
16 MHz is used for the machine clock, and 62.5 ns is used for the count clock of 16-bit PPG timer.

Coding example
ICR07 EQU 0000B7H ;Interrupt control register for the waveform sequencer
PCSR1 EQU 000042H ;PPG period setting register
PDUT1 EQU 000044H ;PPG duty setting register
PCNT1 EQU 000046H ;PPG control status register
OPCR EQU 00008AH ;Output control register
OPDBR0 EQU 003FE0H ;Output data buffer register
WTIF EQU OPCR:9 ;Interrupt request flag bit
;-------Main program------------------------------------------------------------------------------------------------
CODE CSEG
START:
; : ;Assumes that stack pointer (SP) has already been
initialized
AND CCR,#0BFH ;Interrupt disable
MOV I:ICR01,#00H ;Interrupt level 0 (strongest)
MOVW I:PCSR0,#0064H ;Sets the period of the PPG output
MOVW I:PDUT0,#003CH ;Sets the duty ratio of the PPG output
MOVW I:PCNT0,#01100000000000110B
;Enables PPG output in normal polarity
;Enables 16-bit PPG timer, and 62.5 ns clock
;Software triggers PPG
;Select PWM mode
;Clears interrupt flag, and starts counter
MOVW I:OPCR,#0103H ;Enable OPT0 and OPT1 output
;Sets OPDBR0 write method for data transfer
