- bit 6 = 0 to select the esp uart, 1 to select the pi uart †
- bit 4 = 1 if the bits 2:0 are being written
- bits 2:0 = most significant bits of the 17-bit prescalar setting baud rate
pi gpio must be configured for uart, see {{#ask: TBRegisterNumber::$A0 }} ($A0)
† either uart can be redirected to the joystick ports, see {{#ask: PortNumber::$xx37 }} ($xx37{{#ask: PortNumber::$xx37 |mainlabel=- |headers=hide |intro= / |?NumberDec#- }})
