12.2.4 SIO Transmit/Receive Mode Registers

SIO0 Mode Register (S0MOD)
SIO1 Mode Register (S1MOD)
SIO2 Mode Register (S2MOD)
SIO3 Mode Register (S3MOD)
SIO4 Mode Register (S4MOD)
SIO5 Mode Register (S5MOD)
D8
D Bit Name
8 - 10 SMOD
(Serial I/O mode select bit)
(Note 1)
11 CKS
(Internal/external clock select bit)
12 STB (Stop bit length select bit,
UART mode only)
13 PSEL (Parity odd/even select bit,
UART mode only)
14 PEN (Parity enable bit,
UART mode only)
15 SEN (Sleep select bit,
UART mode only)
Note 1 : For SIO2 and 3, the D8 bit is fixed to 0 in hardware. You cannot set the D8 bit to 1 (to choose clock-
synchronous serial I/O).
Note 2 : Has no effect when UART mode is selected.
Note 3 : D12 to D15 have no effect during clock-synchronous mode.
