Field Documentation

p_transfer_rx

transfer_instance_t const* uart_cfg_t::p_transfer_rx

Optional transfer instance used to receive multiple bytes without interrupts. Set to NULL if unused. If NULL, the number of bytes allowed in the read API is limited to one byte at a time.

p_transfer_tx

transfer_instance_t const* uart_cfg_t::p_transfer_tx

Optional transfer instance used to send multiple bytes without interrupts. Set to NULL if unused. If NULL, the number of bytes allowed in the write APIs is limited to one byte at a time.
