12.5 Timebase Register Description
MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
Address:
The timebase has one register, the TBCR, which is used to enable the
timebase interrupts and set the rate.
TBIF — Timebase Interrupt Flag
TBR2–TBR0 — Timebase Rate Selection
Reset:
Read:
Write:
Table 12-1. Timebase Rate Selection for OSCCLK = 32.768 kHz
TBR2
This read-only flag bit is set when the timebase counter has rolled
over.
These read/write bits are used to select the rate of timebase interrupts
as shown in
