The GLOBAL_CONTROLS register enables dynamic power saving in ICSSM*. When GLOBAL_CONTROLS.NOGATE is programmed to ‘0’, it enables auto clock gating in ICSSM* with increased access latency. When this bit is programmed to ‘1’, the clock is continuously active with low latency access.
The GPI signals of ICSSM* can be sourced either from device pins or from PWM_XBAR . This selection can be done on a per signal basis using the registers ICSSM*_PRU*_GPI_SEL, as shown in Figure 6-4.
When the pinmux is configured to choose ICSSM* GPIO function (PR0_PRU*_GPIO*), the control of the output buffer of the device pin can be done using the registers ICSSM*_PRU*_GPIO_OUT_CTRL, as shown in Figure 6-4.
