NOTES:
1. Set registers PS0, PS1, and PS3 after setting other registers.
2. Set the PD9 or PS3 register immediately after the PRC2 bit in the PRCR register is set to 1 (write enable). Do
not generate an interrupt or a DMA or DMACII transfer between these two instructions.
3. P7_0 and P7_1 are N-channel open drain output ports.
