The values of the PRL register are listed in Table 4-1.
Bits 15–8: Processor Release Level (PRL)—This field is an 8-bit, read-only identification
number that specifies the processor release level. The values of the PRL field for the
Am186EM and Am188EM microcontrollers are shown in Table 4-1. Each release level is
numbered one higher than the previous level.
