PSKEY_UART_CONFIG_H4 0x01c0 uint16 0x08a8
If PSKEY_HOST_INTERFACE selects use of H4 then the UART's configuration register is set to the
value of this PS key when it boots.
The UART configuration register is a bitfield and shares its format with PSKEY_UART_CONFIG_BCSP
:
Bit Meaning
0 0 => one stop bit, 1 => two stop bits.
1 0 => no parity bits, 1 => one parity bit.
2 0 => odd parity, 1 => even parity.
3 0 => h/w flow control disabled, 1 => enabled.
4 Set to 0.
5 0 => RTS deasserted, 1 => RTS asserted.
6 Set to 0.
7 0 => non-BCSP/H5 operation disabled, 1 => enabled.
8 Set to 0.
9 Set to 0.
10 Set to 0.
11 Set to 1.
12 0 => H5 operation disabled, 1 => enabled.
13 Set to 0.
14 Set to 0.
15 Set to 0.
The default value, 0x08a8, selects use of hardware flow control, as required by the H4 specification.
