Register Description (DATA2: MAXID and nPOSTR Related)
MAXID3 - 0
ACHTBYP
When the transmit trigger (TXTRG3-0) setting is set to “By the external trigger”, bypass is automatic.
POSTRDLY
Tx = Period of input clock (11 × Tx = 550 ns and 43 × Tx = 2.15 μs @20 MHz input)
POSTRMD
Initializing OUTPUT PORT means Initialization by both the INITIALIZE OUTPUT PORT command and the
assertion of MYRECON in emergency mode (EMGYMD = 1).

Bit 7
Configure the maximum ID number with range 1 to 15 (MAXID4 is fixed to 0)
MAXID3: MSB; MAXID0: LSB
Configuring PSSL = Low causes MAXID3 to be fixed to 0.
Default: MAXID3 - 0 = 1111
Configures the bypass or not for Anti-chatter circuit on input ports.
0: Enable the anti-chatter circuit (default)
1: Bypass (Disable) the anti-chatter circuit
Configures delay time for the OUTPUT PORT strobe (nPOSTR).
0: From the transition of port A to the falling edge of strobe at least 11 times of Tx (default)
1: From the transition of port A to the falling edge of strobe at least 43 times of Tx.
Configures output mode for the OUTPUT PORT strobe signal (nPOSTR).
0: Asserts OUTPUT PORT strobe signal after initializing OUTPUT PORT and after
receiving the OUTPUT DATA packet (default).
1: Asserts only after receiving the OUTPUT DATA packet.
