8-bit Micro-controller
Bit 6 (PWM1E): PWM1 enable bit
0 Î PWM1 is off (default value), and its related pin carries out the PC1 function;
1 Î PWM1 is on, and its related pin will be set to output automatically.
Bit 7 (PWM2E): PWM2 enable bit
0 Î PWM2 is off (default value), and its related pin carries out the PC2 function.
1 Î PWM2 is on, and its related pin will be set to output automatically.

Bit 0 ~ Bit 7 (SPIB0 ~ SPIB7) : SPI data buffer
If you write data to this register, the data will write to SPIW register. If you read this data, it will read the
data from SPIR register. Please refer to figure7
