6.1.7
The time base (TB) is a 64-bit free-running binary counter defined by the MPC500 architecture. The TB
has two independent reference registers which can generate a maskable interrupt when the time base
counter reaches the value programmed in one of the two reference registers. The period of the TB depends
on the driving frequency. The TB is clocked by the TMBCLK clock. The period for the TB is:
The state of TB is not affected by any resets and should be initialized by software. Reads and writes of the
TB are restricted to special instructions. Separate special-purpose registers are defined in the MPC500
architecture for reading and writing the TB. For the MPC561/MPC563 implementation, it is not possible
to read or write the entire TB in a single instruction. Therefore, the mttb and mftb instructions are used to
move the lower half of the time base (TBL) while the mttbu and mftbu instructions are used to move the
upper half (TBU).
Two reference registers are associated with the time base: TBREF0 and TBREF1. A maskable interrupt is
generated when the TB count reaches to the value programmed in one of the two reference registers. Two
status bits in the time base control and status register (TBSCR) indicate which one of the two reference
registers generated the interrupt.
