64KB/36KB/20KB with ISP Flash
& 2KB RAM embedded
9.1.4. Mode 3
The only difference between Mode 2 and Mode 3 is that: in Mode 3, either internal baud rate generator or timer 1 can be
use to specify baud rate.

9.2.1. Mode A
This mode is similar to Mode 2 and 3 of Serial interface 0, 11 bits are transmitted or received: a start bit (0), 8 data bits
(LSB first), a programmable Bit 9, and a stop bit (1). Bit 9 can be used to control the parity of the serial interface: at
transmission, bit TB81 in S1CON is outputted as Bit 9, and at receive, Bit 9 affects RB81 in SFR S1CON.
