13.5.15.4 Special Function Register CANSTA
CANSTA is implemented as a bit-addressable read/write register.
The bit addresses of CANSTA (7 to 0) are DFH to D8H.
Table 67 SFR CANCON in Read access (address DFH to D8H)
Table 68 Description of the CANCON bits in Read access
When reading CANSTA the Status Register of the CAN-controller is accessed.
Table 69 SFR CANCON in Write access (address DFH to D8H)
Table 70 Description of the CANSTA bits in Write access
Writing to CANSTA sets the address of the on-chip MAIN RAM (internal Data Memory) for a subsequent DMA transfer.
