• Manufacturer: Motorola

7.6.1
For details of the functions of bits 2,3,4,6 and 7, see Section 7.5.1.
GWOM — Port G wired-OR mode
SP2R1 and SP2R0 — SPI2 clock rate selects
These two bits, along with the SP2R2 bit, select the SPI clock rate as shown in Table 7-1. Note
that SP2R2 is located in the SP2OPT register, and that its state on reset is zero.
7.6.2
For a description of bits 4,6 and 7, see Section 7.5.2.
7.6.3
For a description of this register, see Section 7.5.3.
7.6.4
For a description of bits 2 and 3, see Section 7.5.4.
