10.7.1 Stack Pointer Limit
The Stack Pointer Limit Register (SPLIM) marks the lower limit of the stack. If the Stack Pointer (SP) has a value lower than SPLIM, a limit check signal is asserted, and the Stack Pointer Limit Error (SPLIM) flag in the Interrupt Flags (INTFLAGS) register is set.
The Stack Pointer Limit Error (SPLIM) flag in the Interrupt Flags (INTFLAGS) register is also routed to the Error Controller.
The CPU.SPLIML and CPU.SPLIMH register pair represents the 16-bit value, CPU.SPLIM. The low
byte [7:0] (suffix L) is accessible at the original offset. The high byte [15:8] (suffix H)
can be accessed at offset + 0x01.
