The r30[20-19] (clk_mode[1:0]) value determines the stop condition for PERIF<m>_CLK. There are 4 options available:
clk_mode_value | Description |
---|---|
0 | Stop low on last RX frame |
1 | Stop high on last RX frame |
2 | Run continuously |
3 | Stop high on last TX bit |
The last RX frame is configured by PRU_ICSS_PRU0_ED_CHm_CFG0_REG[27-16] PRU0_ED_RX_FRAME_SIZEm, and the last TX bit is configured by PRU_ICSS_PRU0_ED_CHm_CFG0_REG[15-11] PRU0_ED_TX_FRAME_SIZEm (where n = 0 or 1 and m = 0 to 2). Each stop condition is shown in Figure 7-33 through Figure 7-36.
