IMASK contains two 8-bit fields, IMASKH and IMASKL. IMASK can be accessed with a 16-bit
read or write, and IMASKH and IMASKL can be accessed with byte reads or writes.
IMASK contains one interrupt mask bit per buffer. It allows the CPU to designate which
buffers will generate interrupts after successful transmission/reception. Setting a bit in
IMASK enables interrupt requests for the corresponding message buffer.
IFLAG contains two 8-bit fields, IFLAGH and IFLAGL. IFLAG can be accessed with a 16-bit
read or write, and IFLAGH and IFLAGL can be accessed with byte reads or writes.
IFLAG contains one interrupt flag bit per buffer. Each successful transmission/reception sets
the corresponding IFLAG bit and, if the corresponding IMASK bit is set, an interrupt request
will be generated.
To clear an interrupt flag, first read the flag as a one, and then write it as a zero. Should a
new flag setting event occur between the time that the CPU reads the flag as a one and
writes the flag as a zero, the flag is not cleared. This register can be written to zeros only.
Both counters are read only, except when the TouCAN is in test or debug mode.
