P30 to P36 function as a 7-bit I/O port. Besides serving as an I/O port, they also function as data I/O and clock
P30 to P33 can drive LEDs directly.
The following operating modes can be specified in 1-bit units.
These pins function as data I/O and clock I/O for serial interfaces CSI1 and UART0.
(a) SI1
(b) SO1
(c) SCK1
(d) R
(e) T
(f) ASCK0
These pins function as a 7-bit I/O port. They can be specified as input or output in 1-bit units using port mode
register 3 (PM3). P30 to P33 are N-ch open drain I/O pins. Mask ROM version can contain pull-up resistors
in P30 and P31 with the mask option. On-chip pull-up resistors can be connected to P34 to P36 by setting pull-
up resistor option register 3 (PU3).
These pins function as data I/O and clock I/O for serial interfaces SIO3 and UART2.
