Public Attributes | |
| uint8_t | pta_mode |
| The PTA mode, see enum sl_wfx_pta_mode_t. | |
| uint8_t | request_signal_active_level |
| Active level on REQUEST signal (PTA_RF_ACT pin), provided by Coex to request the RF, see enum sl_wfx_signal_level_t. | |
| uint8_t | priority_signal_active_level |
| Active level on PRIORITY signal (PTA_STATUS pin), provided by Coex to set the priority of the request, see enum sl_wfx_signal_level_t. | |
| uint8_t | freq_signal_active_level |
| Active level on FREQ signal (PTA_FREQ pin), provided by Coex in 4-wire mode when Coex and WLAN share the same band, see enum sl_wfx_signal_level_t. | |
| uint8_t | grant_signal_active_level |
| Active level on GRANT signal (PTA_TX_CONF pin), generated by PTA to grant the RF to Coex, see enum sl_wfx_signal_level_t. | |
| uint8_t | coex_type |
| The Coex type, see enum sl_wfx_coex_type_t. | |
| uint8_t | default_grant_state |
| The state of the GRANT signal before arbitration at grant_valid_time, see enum sl_wfx_grant_state_t. | |
| uint8_t | simultaneous_rx_access |
| Boolean to allow both Coex and WLAN to receive concurrently, also named combined mode. | |
| uint8_t | priority_sampling_time |
| The time (in microseconds) from the Coex request to the sampling of the priority on PRIORITY signal (1 to 31) | |
| uint8_t | tx_rx_sampling_time |
| The time (in microseconds) from the Coex request to the sampling of the directionality on PRIORITY signal (priority_sampling_time to 63) | |
| uint8_t | freq_sampling_time |
| The time (in microseconds) from the Coex request to the sampling of freq-match information on FREQ signal (1 to 127) | |
| uint8_t | grant_valid_time |
| The time (in microseconds) from Coex request to the GRANT signal assertion (MAX(tx_rx_sampling_time, freq_sampling_time) to 255) | |
| uint8_t | fem_control_time |
| The time (in microseconds) from Coex request to the control of FEM (grant_valid_time to 255) | |
| uint8_t | first_slot_time |
| The time (in microseconds) from the Coex request to the beginning of reception or transmission (grant_valid_time to 255) | |
| uint16_t | periodic_tx_rx_sampling_time |
| The period (in microseconds) from first_slot_time of following samplings of the directionality on PRIORITY signal (1 to 1023) | |
| uint16_t | coex_quota |
| The duration (in microseconds) for which RF is granted to Coex before it is moved to WLAN. | |
| uint16_t | wlan_quota |
| The duration (in microseconds) for which RF is granted to WLAN before it is moved to Coex. | |
Request sent by the host to set the PTA mode, the active levels on signals, the Coex type, to define the timings, quotas, combined mode and default grant state.
Depending on specified PTA mode, every setting is not necessarily used and can then be set to '0'.
The following table indicates the PTA mode for which the setting is significant.
Combined mode is activated during concurrent RX (WLAN and Coex) requests and if SimultaneousRxAccesses is set to '1'.
| Settings | 1-wire WLAN Master | 1-wire Coex Master | 2-wire | 3-wire | 3-wire (combined) | 4-wire | 4-wire (combined) |
