11 Test and Diagnostics
11.1 Diagnostics Control Registers
11.1.3 State Counter Modes Registers
The state counter modes registers control state counter diagnostics, including the breaking of state counter carry
chains, using /FR_COMP as the internal frame reference, and allowing the state counter to roll over early via a
modulo function. For more details, refer to Section 11.2 on page 112.
Table 92. State Counter Modes Registers
11.1.4 Miscellaneous Diagnostics Low Register
The miscellaneous diagnostics low register: bits 2 and 1 allow direct reset of the APLL2 and APLL1 feedback divid-
ers. Bit 0 controls the TST input of the power-on reset cell.
