0 – CPU has no write access to the protected configuration registers
1 – CPU has write access to the protected configuration registers (While CCCR.INIT =1)
0INITR/W1Initialization
0 – Normal Operation
1 – Initialization has started
Note:

The TCAN4550-Q1 handles stop request through hardware. The means that a 1 should not be written to CCCR.CSR (Clock Stop Request) as this will interfere with normal operation. If a Read-Modify-Write operation is performed in Standby mode a CSR = 1 will be read back but a 0 should be written to it.
