Wakeup
19-sibus
NOTE:
Bit manipulation instructions (BSET or BCLR) shall not be used to clear
interrupt flags.
The serial bus interface module is able to wake-up from CPU STOP
mode or Module SLEEP mode by the recognition of a falling edge at the
input Rx. The local mask for the wakeup interrupt is the Wakeup
Interrupt Enable bit (WAKEIE). After wake-up a node configured as
Master should start to send SYNC pulses during tsl_min (refer to
transceiver spec ELMOS 100.34) in order to avoid that the transceiver
enters sleep mode again.
1. The X Bit in the condition code register (CCR) is the interrupt mask for the XIRQ pin
2. The I Bit in the condition code register (CCR) is the global interrupt mask for all HC12 CPU
