Member Data Documentation

◆ address_size

uint32_t _ll_qspi_init_t::address_size

Specifies the QSPI address width. This parameter can be a value of QSPI Address Size.

This feature can be modified afterwards using unitary function ll_qspi_set_address_size().

Definition at line 88 of file gr55xx_ll_qspi.h.

◆ baud_rate

uint32_t _ll_qspi_init_t::baud_rate

Specifies the BaudRate prescaler value which will be used to configure the transmit and receive SCK clock. This parameter can be one even value between 2 and 65534, if the value is 0, the SCLK is disable.

Note
The communication clock is derived from the master clock. The slave clock does not need to be set.

This feature can be modified afterwards using unitary function ll_qspi_set_baud_rate_prescaler().

Definition at line 117 of file gr55xx_ll_qspi.h.

◆ clock_phase

uint32_t _ll_qspi_init_t::clock_phase

Specifies the clock active edge for the bit capture. This parameter can be a value of Clock Phase.

This feature can be modified afterwards using unitary function ll_qspi_set_clock_phase().

Definition at line 112 of file gr55xx_ll_qspi.h.

◆ clock_polarity

uint32_t _ll_qspi_init_t::clock_polarity

Specifies the serial clock steady state. This parameter can be a value of Clock Polarity. This feature can be modified afterwards using unitary function ll_qspi_set_clock_polarity().

Definition at line 108 of file gr55xx_ll_qspi.h.

◆ data_size

uint32_t _ll_qspi_init_t::data_size

Specifies the QSPI data width. This parameter can be a value of Datawidth.

This feature can be modified afterwards using unitary function ll_qspi_set_data_size().

Definition at line 103 of file gr55xx_ll_qspi.h.

◆ inst_addr_transfer_format

uint32_t _ll_qspi_init_t::inst_addr_transfer_format

Specifies the QSPI instruction and address transfer format. This parameter can be a value of QSPI Address and Instruction Transfer Format.

This feature can be modified afterwards using unitary function ll_qspi_set_add_inst_transfer_format().

Definition at line 93 of file gr55xx_ll_qspi.h.

◆ instruction_size

uint32_t _ll_qspi_init_t::instruction_size

Specifies the QSPI instruction width. This parameter can be a value of QSPI Instruction Size.

This feature can be modified afterwards using unitary function ll_qspi_set_instruction_size().

Definition at line 83 of file gr55xx_ll_qspi.h.

◆ rx_sample_delay

uint32_t _ll_qspi_init_t::rx_sample_delay

Specifies the RX sample delay. It is used to delay the sample of the RX input port. This parameter can be a number between 0 and 0x7

Definition at line 123 of file gr55xx_ll_qspi.h.

◆ transfer_direction

uint32_t _ll_qspi_init_t::transfer_direction

Specifies the QSPI transfer or receive mode. This parameter can be a value of Transfer Mode.

This feature can be modified afterwards using unitary function ll_qspi_set_transfer_direction().

Definition at line 78 of file gr55xx_ll_qspi.h.

◆ wait_cycles

uint32_t _ll_qspi_init_t::wait_cycles

Specifies the QSPI dummy clock. This parameter can be one of the following values: 0 ~ 31.

This feature can be modified afterwards using unitary function ll_qspi_set_wait_cycles().
