26.13.11 Note on CTL Interrupt

After a reset, the CTL circuit is in the VISS discrimination input mode.
Depending on the CTL pin states, a false PB-CTL input pulse may be recognized and an interrupt
request generated. If the interrupt request will be enabled, first clear the CTL interrupt request
flag.
