Figure 15:

SPI Read Data Frame

The data is sent on the MISO pin. The parity bit PARD is

calculated by the ASAS5247 for the 16-bit data frame. If an error

is detected in the previous SPI command frame, the EF bit is set

high. The SPI read is sampled on the rising edge of CSn and the

data is transmitted on MISO with the next read command, as

shown in Figure 16.
