Table 498. SCT pin description
The register addresses of the State Configurable Timer are shown in
of the SCT registers, the register function depends on the setting of certain other register
bits:
Function name
CTIN_[7:0]
CTOUT_[15:0]
1. The UNIFY bit in the CONFIG register determines whether the SCT is used as one
2. The REGMODEn bits in the REGMODE register determine whether each set of

32-bit register (for operation as one 32-bit counter/timer) or as two 16-bit
counter/timers named L and H. The setting of the UNIFY bit is reflected in the register
map:
– UNIFY = 1: Only one register is used (for operation as one 32-bit counter/timer).
– UNIFY = 0: The L and H registers can be accessed by a 32-bit read or write
Typically, the UNIFY bit is configured by writing to the CONFIG register before any
other registers are accessed.
Match/Capture registers uses the match or capture functionality:
– REGMODEn = 1: Registers operate as match and reload registers.
operation or can be read or written to individually (for operation as two 16-bit
counter/timers).
