Reserved bits
Master enable TOCXA₄, TOCXB₄
These bits enable or disable output
settings for pins TOCXA₄ and TOCXB₄
Master enable TIOCA₃, TIOCB₃, TIOCA₄, TIOCB₄
These bits enable or disable output settings for pins
TIOCA₃, TIOCB₃ , TIOCA₄, and TIOCB₄
TOER is initialized to H'FF by a reset and in standby mode.
Bits 7 and 6—Reserved: Read-only bits, always read as 1.
Bit 5—Master Enable TOCXB4 (EXB4): Enables or disables ITU output at pin TOCXB₄.
Bit 5: EXB4
0

Description
TOCXB4 output is disabled regardless of TFCR settings (TOCXB4 operates as
a generic input/output pin).
If XTGD = 0, EXB4 is cleared to 0 when input capture A occurs in channel 1.
TOCXB4 is enabled for output according to TFCR settings
(Initial value)
Bit 4—Master Enable TOCXA4 (EXA4): Enables or disables ITU output at pin TOCXA₄.
Bit 4: EXA4

Description
TOCXA4 output is disabled regardless of TFCR settings (TOCXA4 operates as
