Figure 6-12:
Operation of DMA Channel 2/3
Remark:
n = 0, 1
(number of TMR channel)
x = n + 2 (number of DMA transfer channel)
Initialize destination pointer to 1st
TMR compare register:
m 2 SARx + Address of TRnCCR5
DEx bit = 1 ?
DEx bit newly
written ?
INTTRnOD
occurred ?
INTTRnCD
occurred ?
Increment destination pointer:
m m + 2
Transfer content from iRAM to TMRn
compare register: (m)
(MARx)
Increment source pointer:
MARx MARx + 2
m > Address of
TRnCCR0 ?
Decrement DMA transfer count register:
DTCRx DTCRx - 1
DTCRx = 0?
Set DMA transfer status bit: DMASx = 1
Generate interrupt signal (INTDMAx)
no
yes
no
yes

DMA transfer will be enabled
by write access to the
