SPIB7
Bit0 ~Bit1: Unused register. These two bits are not allowed to use.
Bit2 ~ Bit7 (P62 ~ P67) : 6-bit PORT6(2~7) I/O data register
User can use IOC register to define input or output each bit.

Bit 6 (PWM1E): PWM1 enable bit
Bit 7 (PWM2E): PWM2 enable bit
P67
Bit 0 ~ Bit 7 (SPIB0 ~ SPIB7) : SPI data buffer
Bit 0 ; Bit3 ~ Bit 7 (P73 ~ P76) : 5-bit PORT7 I/O data register
Bit1~2, Bit 7: Unused register. These three bits are not allowed to use.
Bit 0(RAM_B0) : Data RAM bank selection bits
Bit 1 : (undefined) not allowed to use. This bit must clear to 0.

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

A specified value keeps the output of PWM1 to stay at high until the value matches with TMR1.

User can use IOC register to define input or output each bit.
Each bank has address 0 ~ address 255 which is total 256 (0.25k) bytes RAM size.
Data RAM bank selection : (Total RAM = 0.5K)

PWM1 is off (default value), and its related pin carries out the PC1 function;
PWM1 is on, and its related pin will be set to output automatically.
PWM2 is off (default value), and its related pin carries out the PC2 function.
PWM2 is on, and its related pin will be set to output automatically.
