5.2.2 System Configuration Registers
This section discusses the system configuration registers.
5.2.2.1 System General Purpose Register Low (SGPRL)
The system general purpose register low (SGPRL), shown in Figure 5-10, can be used by software for any
purpose. The values set in this register have no effect on the internal hardware.
Table 5-19 defines the bit fields of SGPRL.

5.2.2.2 System General Purpose Register High (SGPRH)
The system general purpose register high (SGPRH), shown in Figure 5-11, can be used by software for
any purpose. The values set in this register have no effect on the internal hardware.
Table 5-20 defines the bit fields of SGPRH.
