This section describes transfer operation example 5.
DES Values at Transfer Start
Below are details of transfer operation example 5.
Table 4-8 DES Values at Transfer Start in Transfer Operation Example 5
Area
DES No.
Value
1st-DES
DES0
DES0 = 0x612806B1
DV = 01 : DES close process to be executed at the end of transfer
MODE = 1, TW = 10 : Mode 1, 32-bit (word) transfer
ORL = 101 : OuterReload of DES1 <= DES4, DES3 <= DES6
SAC = 001 : Increment of TW×1 with InnerReload.
DAC = 000 : Increment of TW×1 without InnerReload.
CHRS = 101000 : There is a Chain Start in the succeeding DES; no interrupt flag has been set.
DMSET = 0 : No DQMSK[n] is set in a DES close process.
CHLK = 0 : No Chain lock
ACK = 01 : Set ACK to "01" as the DES is directly started by the hardware.
PCHK = 0110 : Parity
DES1
ORM = 0x0002, IIN = 0x02, IRM = 0x02
DES2
SA = 0x00000000
