programmed for input or output. Reset operation initializes all pins as input port pins.
All bits in the output latch register (P9) are set to “1”. In addition to functioning as a
general-purpose input/output port, Port 9 can also function as input/output pins for
serial channels 0 and 1. This alternate function can be enabled by writing “1” to
respective bits of the Port 9 function register (P9FC). Upon reset the P9CR and P9FC
registers are all initialized to “0”, setting all pins as input port pins.
output pins for serial channels 0 and 1.

Port 9 is a 6-bit general-purpose input/output port. Each bit can be individually
P90 and P93 can be used either as general-purpose input/output port pins or TXD
The output buffer is configurable as an open-drain output using the <ODE90> and
