I'm using the K70 150MHz with MQX 4.2 and KDS.
The datasheet of the K70 (Rev.3 November 2014) indicate only the register CANx_IMASK1/ CANx_IFLAG1, not the IMASK2/IFLAG2...
But in KDS3.0 with EmbSys Register I can visualise IFLAG2/IMASK2.
But on Can Clock Turn on in BSP init (sim->SCGC6 |= SIM_SCGC6_FLEXCAN0_MASK;)
only IFLAG1/IMASK1 are set to 0, IMASK2/IFLAG 2 not change and MASK2 stay to 0x80008000???
Also, in Datasheet §53.3.12 (CANx_CTRL2) on RFFN description, there is a table indicate how many remaining available mailboxes which can up to 64...
So if there is realy 64 Maibox, the Clock turn on allow automaticcaly to Reset MASK/IFLAG1 to 0 but not the IMASK2/IFLAG2, in which case, MQX 4.2 has a bug by not setting the default value register to 0..?
So are they 32 or 64 mb in K70
