13.2.2 GDMA slave mode
Bits MODE[1:0] = 00: data strobes DIOR (read) and DIOW (write); see Figure 32
Bits MODE[1:0] = 01: data strobes DIOR (read) and DACK (write); see Figure 33
Bits MODE[1:0] = 10: data strobes DACK (read and write); see Figure 34
Table 109. GDMA slave mode timing parameters
VCC(I/O) = 1.65 V to 3.6 V; VCC(3V3) = 3.3 V; VGND = 0 V; Tamb = 40 °C to +85 °C; unless otherwise specied.
