PT
Parity type. PM and PT together select parity type (PM = 0x) or determine whether a data or address
character is transmitted (PM = 11).
1–0
B/C
Bits per character. Select the number of data bits per character to be sent. The values shown do not
include start, parity, or stop bits.
00 5 bits

16.3.2 UART Mode Register 2 (UMR2n)
UART mode registers 2 (UMR2n) control UART module configuration. UMR2n can be
read or written when the mode register pointer points to it, which occurs after any access to
UMR1n. UMR2n accesses do not update the pointer.
