Wake-up Timer Period Register
The Wake-up Timer Period register sets the wake-up interval for the TRC101. After setting the wake-up
interval, the WKUPEN (bit 1 of Power Management Register) should be cleared and set at the end of
every wake-up cycle. To calculate the wake-up interval desired, use the following:
where M[7..0] = decimal value 0 to 255 and R[4..0] = decimal value 0 to 31.
Bit [15..13] – Command Code: These bits are the command code that is sent serially to the processor
that identifies the bits to be written to the Wake-up Timer Period register.
Bit [12..8] – Exponential: These bits define the exponential value as used in the above equation. The
value used must be the decimal equivalent between 0 and 31.
Bit [7..0] – Multiplier: These bits define the multiplier value as used in the above equation. The value
used must be the decimal equivalent between 0 and 255.
