Description
PMode1 Sensitivity Counter. Counter that controls the GLMC’s sensitivity to entering
PMode1 power down mode. If PMode1 is enabled, PM1_SENS starts counting down
from its loaded value whenever the GLMC becomes idle. If it times out and the GLMC is
still idle, the GLMC goes into PMode1. If, however, the GLMC resumes activity before
time-out, the counter is reset to its loaded value and PMode1 is not entered. (Default =
0h)
PMode0 Sensitivity Counter. Counter that controls the GLMC’s sensitivity to entering
PMode0 power down mode. If PMode0 is enabled, PM0_SENS starts counting down
from its loaded value whenever the GLMC becomes idle. If it times out and the GLMC is
still idle, the GLMC goes into PMode0. If, however, the GLMC resumes activity before
time-out, the counter is reset to its loaded value and PMode0 is not entered. (Default =
6h, to allow 32-bit bursts to finish).
