In this case, leave floating. • IRQ_1: if the chip is never used in Tx FSK mode (DCLK connection is not compulsory in Rx and Tx OOK modes). In this case, leave floating. • MISO: if no read register access is needed. In this case, pull-up to VDD through a 100 k Ω resistor. In addition, NSS_DATA pin (unused in continuous mode) should be pulled-up to VDD through a 100 k Ω resistor. Please refer to Table 13 for RF63 ‟s pins configuration 5.3.6. Continuous Mode Example • Configure all data processing related registers listed below appropriately. In this example we assume that both Bit synchronizer and Sync word recognition are on. Table 19: Relevant Configuration Registers in Continuous Mode (data processing related only) Tx Rx Description MCParam Data_mode_x X X Defines data operation mode (- Continuous) IRQParam Rx_stby_irq_0 X Defines IRQ_0 source in Rx mode RXParam Sync_on X Enables Sync word recognition Sync_size X Defines Sync word size Sync_tol X Defines the error tolerance on Sync word recognition SYNCParam Sync_value X Defines Sync word value Tx Mode: • Go to Tx mode (and wait for Tx to be ready, see Figure 50) • Send all packet ‟s bits on DATA pin synchronously with DCLK signal provided on IRQ_1 • Go to Sleep mode Rx Mode: • Program Rx interrupts: IRQ_0 mapped to Sync (Rx_stby_irq_0= ”00”) and IRQ_1 mapped to DCLK (Bit synchronizer enabled) • Go to Rx mode (note that Rx is not ready immediately, see Figure 49) • Wait for Sync interrupt • Get all packet bits on DATA pin synchronously with DCLK signal provided on IRQ_1 • Go to Sleep mode |
