Description

HSPI timing configuration register

Fields

DCYC

Number of dummy cycles This field defines the duration of the dummy phase. In both SDR and DTR modes, it specifies a number of CLK cycles (0-31).
DHQC

Delay hold quarter cycle

0 (B_0x0): No delay hold

1 (B_0x1): 1/4 cycle hold
SSHIFT

Sample shift By default, the HSPI samples data 1/2 of a CLK cycle after the data is driven by the external device. This bit allows the data to be sampled later in order to consider the external signal delays. The software must ensure that SSHIFT = 0 when the data phase is configured in DTR mode (when DDTR = 1.)

0 (B_0x0): No shift

1 (B_0x1): 1/2 cycle shift
