DMACII Index

The DMACII index is an 8- to 32-byte data table, which stores parameters for transfer mode, transfer counter,
source address (or immediate data), operation address as an address to be calculated, destination address, chain
transfer address, and end-of-transfer interrupt address.
The DMACII index must be located on the RAM area.
Figure 14.2 shows a configuration of the DMACII index. Table 14.2 lists an example configuration of the
DMACII index.
Details of the DMACII index are described below. Set these parameters in the specified order listed in Table
14.2, depending on DMACII transfer mode.
MOD is two-byte data and required to set transfer mode. Figure 14.3 shows a configuration for transfer mode.
COUNT is two-byte data and required to set the number of transfer.
SADR is two-byte data and required to set a source memory address or immediate data.
OADR is two-byte data and required to set a memory address to be calculated. Set this data only when using the
calculation transfer function.
DADR is two-byte data and required to set a destination memory address.
CADR is four-byte data and required to set the starting address of the DMACII index for the next transfer. Set
this data only when using the chain transfer function.
IADR is four-byte data and required to set a jump address for end-of-transfer interrupt processing. Set this data
only when using the end-of-transfer interrupt.
The abbreviations shown in parentheses( ) for each parameter are used in this section.
Transfer mode (MOD)
Transfer counter (COUNT)
Transfer source address (SADR)
Operation address (OADR)
Transfer destination address (DADR)
Chain transfer address (CADR)
End-of-transfer interrupt address (IADR)
NOTES:
Place the DMACII index in the RAM. Necessary data must be set top-aligned without any space. For example, if not using the
calculation transfer function, assign a transfer destination address to BASE+6.
The starting address of the DMACII index must be assigned to the interrupt vector of the peripheral function interrupt triggering
a DMACII request.
