TOCV register of MCAN: read-only or not?

[lpelton]

The LPC546xx user manual says, in section 35.8.7, regarding the Timeout counter in the MCAN module:

"When the timeout counter is operating in continuous mode, a write
to the TOCV register presets the counter to the value configured in the TOP bits of
the TOCC register and continues down-counting."

However, the TOCV register is marked as read-only in Table 712 of the user manual, and attempting to write to it using the supplied "CAN_Type" defined in LPC54608.h (from the SDK), results in a compiler error, because the register is defined as read-only.

Before I start experimenting with writing the register directly without going through "CAN_Type":

Does anyone know if this register is really read-only, and if so, how is it refreshed since the method described in the user manual would be impossible?

Thanks.

Hi Larry

This is a document defect. TOCV is writable. This issue is reported, we will correct is in next release.

Have a great day,
