How to interface with a >16-bit SPI device?

How to interface with more than 16-bit SPI devices, like a 20-bit ADC (e.g. ADS8900B)?All but STM32H7 have 16-bit buffers (see AN5543). Are there ways to effectively use a 'lesser' microcontroller (e.g. STM32G0 or -G4)?

I am working on communication between STM32H735(STM32H735G-DK) and STM32H745(STM32H745I-Disco) via FDCAN according to the official tutorial( he used different MCUs). But I couldn't receive any message by RxData, any idea?

Here is the software setting:​For STM32H735(STM32H745 is the same but with different ID):-Defines:/* USER CODE BEGIN PV */FDCAN_TxHeaderTypeDef TxHeader;FDCAN_RxHeaderTypeDef RxHeader;uint8_t TxData_Node1_To_Node2[] = {0x10, 0x32, 0x54, 0x76, 0x98, 0...
