NOTES:
1. P345CON will be initialized as “50H” to set P3.4 and P3.5 into open drain output mode after reset operation.
2. S3F80JB has P4CONH, P4CONL and P4CON as port4 control registers. P4CONH and P4CONL will be initialized
as the C-MOS input with pull up mode after reset. On the other hand, P4CON will be initialized as open-drain output
mode. After reset, status of port4 is decided by P345CON.0 bit. So port4 reset status will be initialized as open-drain
output mode.
