The TSR registers are 8-bit registers that indicate the status of each channel. The TPU has six TSR
registers, one for each channel. The TSR registers are initialized to H'C0 by a reset, and in
hardware standby mode.
Bit 7—Count Direction Flag (TCFD): Status flag that shows the direction in which TCNT
counts in channels 1, 2, 4, and 5.
In channels 0 and 3, bit 7 is reserved. It is always read as 1 and cannot be modified.
Bit 6—Reserved: This bit is always read as 1 and cannot be modified.
Bit 5—Underflow Flag (TCFU): Status flag that indicates that TCNT underflow has occurred
when channels 1, 2, 4, and 5 are set to phase counting mode.
In channels 0 and 3, bit 5 is reserved. It is always read as 0 and cannot be modified.
Bit 4—Overflow Flag (TCFV): Status flag that indicates that TCNT overflow has occurred.
