FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Figure 30. HS Operation When Cyclic Sense Is Selected
LOW POWER CONTROL REGISTER (LPC)
Tables 36 through 40 contain the Low Power Control Register information. The LPC register controls:
The state of HS in Stop and Sleep modes (HS permanently OFF or HS cyclic).
Enable or disable of the forced wake-up function (SBC automatic wake-up after time spent in Sleep or Stop modes; time is
defined by the TIM2 sub register).
Enable or disable the sense of the wake-up inputs (Lx) at the sampling point of the Cyclic Sense period (LX2HS bit). (Refer to
Reset Control Register (RCR) on page 49 for details of the LPC register setup required for proper cyclic sense or direct wake-
up operation.
The LPC register also reports the CANH and RXD diagnostic.
