12.2 DMA Transfer Cycles
Table 12.2 DMA Transfer Cycles
-: This condition does not exist.
Table 12.3 Coefficient j, k
NOTES:
8-bit transfer
(DMBIT =1)
16-bit transfer
(DMBIT = 0)
Any combination of even or odd transfer read and write addresses is possible.
Table 12.2 lists the DMA Transfer Cycles. Table 12.3 lists the Coefficient j, k.
The number of DMAC transfer cycles can be calculated as follows:
No. of transfer cycles per transfer unit = No. of read cycles ✕ j + No. of write cycles ✕ k
k
j
Transfer Unit
1. Depends on the set value of the PM20 bit in the PM2 register.
2. Depends on the set value of the CSE register.
