Any time (always zero if not in a test mode)
Only while SMOD = 1 (TEST or BOOT modes)
0 – Normal operation (trap on illegal opcodes)
1 – Stop giving LIR when an illegal opcode is found
This test mode allows testing of all illegal opcodes serially without servicing an
interrupt after each illegal opcode is received. LIR (inactive for illegal opcodes) is
used to monitor correct CPU operation.
0 – Normal operation
1 – Clock S (Scaled) from the PWM timer is output to and readable on the PWSCAL
0 – Normal operation
1 – The Condition Code bits H, N, Z, V, and C are driven out of the 5 most significant
0 – Normal operation
1 – 16-bit free running timer counter 1 is divided into 8-bit halves and the prescaler is
0 – Normal operation
1 – Regardless of other control bit states, COP and clock monitor will not generate a
When the device is reset in test or bootstrap mode (SMOD = 1), the DISR bit is initialized
to 1 so that resets from the COP and clock monitor are disabled. When reset in normal
modes, the DISR bit is initialized to 0.
