(15) CAN global interrupt enable register (CGIE)
The CGIE register is used to issue interrupt requests for global interrupts.
This register can be read/written in 16-bit units.
Cautions 1. Both bitwise writing and direct writing to the CGIE register are prohibited. Attempts to
write directly to this register may result in operation faults, so be sure to follow the
sequence described in 11.9 Cautions on Bit Set/Clear Function.
2. When writing to the CGIE register, set or clear bits according to the register
configuration during a write operation.
