Bits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 – NONSEC H2PB_NONSEC_INIT_VAL[k] is the initial value of this bit at Reset. Writing a 1 to this bit clears the non-security bit for APB Slave k, k=63...32. Writing a 0 does nothing. Reading this bit delivers the current value of non-security bit of APB Slave k, k=63...32. The write command is accepted only if bit H2PB.WPCTRL.WPEN is not set. Accessing this register is also subject to security checks depending on the value of bit H2PB.CTRLA.SECEN A write to any bit when this register is write-protected results in an error message being returned.
